The scope of this master thesis is to build an (semi)automatic system to train a Siamese net to find the similarity of the fasteners (namely bolts, nuts, screws and washers). Using the output of the Siamese net, the system should group and sort the fasteners in similar groups (in a fine-grained manner. For example it should put all the AS1800 bolts in one group and all the MS2650 bolts in another one). To successfully undertake this thesis, you need to have solid knowledge on machine learning and convolutional neural networks, together with experience in Python programming and working with at least one deep learning framework (Keras, PyTorch, TensorFlow).

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.

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.

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.

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