Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...

Recently, the process of fish species classification has become one most challenging problems addressed by researchers. In this work, a robust scheme to classify images based on feature extraction from shape signatures is proposed. First, image contour fitted using common approaches named radial basis function neural network (RBFNN) fitting obtain centroid. Afterward, prominent features signatu...

Although Covid-19 caused by the SARS-COV-2 virus, is a deadliest disease, many people experienced mild symptoms and were recovered soon. In this paper, coronavirus can be easily detected using CT scan images of affected patients. Initially, are pre-processed filters like Median filter Noise adaptive fuzzy switching median filter, then quality measurements MSE, PSNR calculated. After preprocessi...
