Automotive Division Internship 2022
Motion estimation using neural networks
Human motion modeling is a continuous problem in the area of computer vision. Different approaches to estimating movement were made such as linear approximation, Kalman Filters (EKF and UKF), neural networks, etc. The purpose of this internship is to improve the performance of an existing multiple object tracking model by adding a neural network as a motion model extension.
Free Road Space Detection using CARLA Simulator
Accumulating a large amount of data is hard to come by. With improvements in photo-realistic simulation, using artificially generated data should be considered. This topic should investigate how the training on such data will translate to the real world. In order to do that, the idea is to generate an adequate amount of artificial data and use it to train a CNN. For evaluation of its performance, both artificial data and open-source real-world data will be used.
Vehicle state estimation using Particle filter
The Kalman filter is an optimal state estimator if we assume that errors have a normal (Gaussian) distribution, and the dynamic model and measurement model are both linear. The dynamic model of interest is a car, for which in every step we have a measurement from the vision camera. The dynamic model of the system is not linear which requires a nonlinear state estimation technique to be used.
The most common nonlinear state estimation algorithms are EKF (Extended Kalman Filter), UKF (Unscented Kalman Filter), and Particle Filter. The goal of this task is to compare the EKF and Particle filter state estimation accuracies. The EKF results are already available, while the particle filter implementation needs to be done to compare the mentioned results.
Road Lane Detection and Classification based on CNNs
Road lane detection systems play a crucial role in the context of Advanced Driver Assistance Systems (ADASs) and autonomous driving. Such systems can lessen road accidents and increase driving safety by alerting the driver in risky traffic situations. Additionally, the detection of lanes with their left and right boundaries along with the recognition of their types is of great importance as they provide contextual information. Lane detection is a challenging problem since road conditions and illumination vary while driving.
The goal of the internship is to investigate the use of a CNN-based regression method for detecting road lane boundaries. Additionally, lane classification needs to be performed to categorize previously detected lane boundaries.
Merging disparity images
A car, while driving, collects disparity images from its camera (stereo or mono with CNN). The goal of this internship is to implement an algorithm that will merge disparity data from different frames to get more accurate disparity data. The algorithm will involve matching similar points and running optimization on points in the field of view. The key part of the algorithm is removing redundant points from the field of view.
Computationally Efficient Visual Transformers
Visual Transformers are a fast-growing model architecture as of late in the field of Computer vision. The purpose of this internship is to train a visual transformer (or use an existing transformer available online as open source) and use it as a baseline to try and make it more efficient without hurting the performance. The focus will be on a non-dense tasks such as image recognition to facilitate the necessary setup and simplify the reuse of open-source resources.
Generating Pedestrian Data in Real Scene and Beyond
Pedestrian detection requires a lot of data, and the process of collecting and labeling data can be very cumbersome and time-consuming. One way to address this issue is to develop a General Adversarial Network that will generate labeled pedestrian data and then add that data to the training data of pedestrian detector. The purpose of this internship is to implement such a network and show that it can be used to improve pedestrian detection performance.
Generating realistic traffic images using a CycleGAN
Acquiring enough annotated data of certain traffic scenarios is difficult (sometimes borderline impossible, e.g. a cutting in a fire truck on a highway). Creating those scenarios in a simulator and rendering a realistic version of them using a CycleGAN would save a lot of trouble. CycleGANs have shown that they provide great results when trained on unpaired examples which makes them suitable here. The goal of the internship is to train a CycleGAN to render realistic images of predefined rare traffic situations.
Face Technology Internship 2022
A game based on emotion recognition
Work on introducing new features to a fun game that utilizes your facial movements, expressions, and emotions to smash targets and score points. It is an exciting opportunity to code a new game logic, as well as introduce new features and graphics.
Make-up style transfer using color-aware GAN
GANs have revolutionized the fields of photorealistic image synthesis, image-to-image translation and style transfer. The research community is now mainly focused on controlling different aspects of image synthesis using GANs.
Join us in discovering how to use the CA-GAN model to modify the colors of a specific face area (e.g. lips) and transfer them to another image while keeping the rest of the image intact. The goal of this project is to set up a training framework with the CA-GAN model and train it in a weakly supervised manner.
Automotive Division Internship 2021
Sound classification using CNN
Convolutional neural networks proved to be very effective for image processing, and are increasingly being used for sound processing. Indeed, by computing spectrograms of audio signals, we obtain visual representations of their spectrum of frequencies. These images can then be readily used in CNNs. The goal of the project is to make a brief review of the literature, implement a CNN for sound classification for an application of choice, and experiment with different hyperparameters, particularly those specific to audio data.
GAN for generating adverse weather conditions
Adverse weather conditions such as rain or snow can have a significant impact on autonomous driving performance. At the same time, such data can often be difficult to obtain. Therefore, advanced data augmentation techniques can be used to expand existing datasets. One of the newer approaches is to use a generative adversarial network (GAN) to generate synthetic data. The goal of this project is to develop a GAN for generating adverse weather condition scenarios.
Automatic Emergency Braking Environment
Automatic emergency braking (AEB) is a staple of modern advanced driver-assistance systems. Its purpose is to mitigate crashes by initiating braking automatically when hazardous conditions arise. The purpose of this project is to explore the existing AEB algorithms in the available body of scientific work and to develop a custom algorithm and testing environment evaluating the potential for AEB activation on a given dataset and its resimulations given different changes in the object detection and tracking pipeline. The solution is expected to blend seamlessly with the existing environments using the existing resimulation pipelines and build systems.
Automotive Division Internship 2020
Generate artificial data using generative adversarial network
Data collection and data marking are usually done manually and can prove to be a tedious, expansive and error-prone process. In order to increase the amount of data and improve robustness of a dataset, artificial data approaches can be used. The goal of this internship project is to use generative adversarial network (GAN) to generate usable artificial data. The student will learn how to implement GAN, train GAN on in-house dataset and have an opportunity to further investigate different models and approaches to improve results. Prior experience in the field of machine learning is preferable, but not mandatory. The estimated duration of this project is six to eight weeks.
Data Reduction: Removing Uninformative Samples
Consider developing a supervised learning method with data stemming from a video, for instance a forward-looking camera for an autonomous vehicle. It is guaranteed that many training samples coming from consecutive frames of a video will be too similar. Such (almost) repetitive samples may lead to overfitting, while at the same time significantly increasing training time. The goal of this internship project is to develop a preprocessing step to detect and remove such samples. The task can and will be tackled in different ways, including “conventional” methods and ML algorithms, and gradually progressing from simpler to more complex formulations of the problem.
Object tracking with UKF (for constrained nonlinear systems).
This topic is in the area of object tracking applied in automotive industry. During the internship period, the student will get an insight into modelling a complex system behaviour such as behaviour of a vehicle as well as how to utilize Kalman filter for object tracking. Furthermore, the student will gain practical knowledge with implementation of Extended Kalman Filter, Unscented Kalman filter, and, time allowing, introduction of state constraints in Kalman filtering. Knowledge of estimation theory as well as basic understanding of linear algebra are needed to successfully finish this project. State constraints are an interesting topic and successfully implemented in model predictive control, but there are also articles that suggest that they can be used with EKF and UKF as well. During this internship, it is encouraged to investigate approaches how to do it, with an input from mentor, and try to implement it in UKF. If the work proves engaging and estimation of work inadequate, the internship can be extended for two more weeks. However, if for any reason the implementation cannot be done, just getting an insight in state constraints with Kalman filters would be considered beneficial.
Using a game engine to create synthetic training data
Obtaining real world data needed to train a deep neural network is usually a challenging, costly and time consuming task. The most labor intensive part is manually marking a large amount of data for supervised learning. One way to overcome this issue is to create synthetic data that can be automatically marked using a game engine. The goal of this project will be to create a rather innovative synthetic “domain randomized” dataset similar to the one described in this article that can be used to train a traffic light recognition CNN.
Learning from image: CNN & Mono Depth
This document presents an internship project developed for Visage Technologies AD. The estimated duration of this project is six to eight week. During this period it is expected that a student will get a brief picture about vision system for vehicles, understand convolution neural networks (CNNs), how to design them, go through the learning process and analyse the output. A student should be able to read a scientiﬁc paper and get a critical overview of the work. The practical part of the project includes implementing CNN for mono depth, running training on public data set (e.g. KITTI), tuning hyper-parameters analysing results. To successfully ﬁnish the project, a student has to have good programmer skill and some understanding of machine learning. Knowledge about deep learning and CNN would be preferable, but it is not mandatory. Our mentors will be there to give you advice and discuss the literature. They will also help you organise your work and give you some useful tips through the review process.
