Image compression is one of the essential methods of image processing. Its most prominent advantage is the significant reduction of image size allowing for more efficient storage and transfer. However, lossy compression is associated with the loss of

Fast Dictionary Matching for Content-based Image Retrieval

Autor: Najgebauer, Patryk, Rygal, Janusz, Nowak, Tomasz, Romanowski, Jakub, Rutkowski, Leszek, Voloshynovskiy, Sviatoslav, Scherer, Rafal

This paper describes a method for searching for common sets of descriptors between collections of images. The presented method operates on local interest keypoints, which are generated using the SURF algorithm. The use of a dictionary of descriptors

CVA-GNN: Convolutional Vicinity Aggregation Graph Neural Network for Point Cloud Classification

Autor: Scherer Rafal, Wojciechowski Adam, Najgebauer Patryk, Walczak Jakub

Publikováno v: IJCNN

Point cloud classification is highly dependent on how points' features are extracted and aggregated. The graph-based feature extraction strategies are currently used. Not only point coordinates are taken into consideration but also neighbourhood pair
