Movie-Recommendation-System
In order to take advantage of collaborative filtering and implement a movie reccomendation system, we used Pearson's correlation coefficient, so as to compute k-nearest neighbors for a specific user. Eventually, through genetic operators, such as rank based selection,unifrom crossover and random mapping, we could provide a list of movies for this specific user.
Digital-Image-Watermarking
Waterkmarking an image, both in spatial and frequency domain, using, on a random order, the blocks of an equal size binary image. The order is specified by a pseudorandom sequence generator.
GAN-tutorial
testing pytorch and pytorch lightning on a simple GAN architecture on MNIST
Image-Compression
Testing the trade off of image compression, by using DCT coefficients, both in zonal and threshold coding.
Patras-Crowdsourcing
A crowdsourcing web application, which manipulates location data, in order to compute every user's statistics and also to display their location history on a heatmap.
Shape-Description
Using Fourier Descriptors, in order to describe the shape of a leaf, after the image's segmentation.
