 Theses and Guided Researches:

 Please find underneath the offered, in progress and finished topics. Generally, I work on machine learning assistance in overhaul processes. It covers different industrial use cases like classification, detection and localization of fasteners, tools and machineries and giving the users information about the next steps. In case you are interested to work on such topics and can't find enough information on this page, you can write me an email, including your transcript of records and CV. Important: Most of the tasks and challenges in my work need knowledge and experience in python programming, OpenCV and machine learning (in particular Convolutional Neural Nets). Please consider this before sending thesis requests.

Master's Thesis
Providing the Next-Step-Information in Overhauling Processes

An expert level know-how is considered as one of the most important factors in dealing with overhauling processes. What has been already done and what has to be done now? The aim of this master thesis is to be able to understand the process, the already done tasks and still to-do tasks using the computer vision and machine learning based approaches. The challenge is to come up with a proper representation of the whole process to the system that helps us to fetch the needed information.
Bachelor's Thesis
Getting Depth Image of Small Parts Using Multi-Cameras

Since the small parts and fasteners are scale-variant (which means that with scaling them we'll end up having another small part), classification of them needs a fixed camera to ensure that the distance between the camera lens and the object is always fixed. However, using two or more cameras, we are able to get the depth information of the objects, including their size. In this bachelor thesis, you will work on getting these depth images, using two or more cameras. The true challenge is to consider the small parts characteristics (their small size and their shiny surface) and find solutions to handle them.
Master's Thesis
A Multi-view CNN Approach to Classify Nuts in Overhauling Processes

A new approach to create datasets for classification of different nuts, considering the inner threads and camera angle. The challenge is to preserve the size information of the small part, using a fixed camera and fixed distance to that, while pointing out the camera lens to the nut in specific angles that it can capture its threads, length and overall shape. Using this setup and also other pictures, you will train a model with convolutional neural network to classify different nuts.

Creating a model to detect damaged small parts (screws, bolts, nuts, pins, washers, etc.) in overhauling industrial machineries, using deep learning and convolutinal neural networks
Master's Thesis
Using Synthetic Data for Classification of Small Parts
Advisor
Sajjad Taheri
Author
Amr Abdelraouf
Date
15.03.2018
Studying methods to create datasets from 3D models and use them in training a model for small parts classifier. This method will be compared with the normal manually photographing approach in terms of usability of dataset creation and performance of the classifiers.

Implementing a Speech Recognition System, which can learn fro the user input. The idea is to build an application to be able to monitor the system performance an give it feedback regarding the recognized phrases. These sample, together with the corrected labels, will be used to retrain the model to improve the performance.
