Algorithm for image processing using a frequency separation method

Abstract

The use of high-resolution images is becoming increasingly widespread today. This domanin continuously shows the need for these images to be analyzed and processed. The fields in which images are used and their processing are increasingly broad, from different branches of engineering to medicine, and so on. The emergence of various algorithms for processing information obtained by encoding images is a vast field and is constantly evolving. This paper extends a previous study on the application of image processing methods using algorithms involving the use of frequencies. We will discuss issues related to the treatment and improvement of the quality of the images. The algorithm proposes decomposing an image into the representation in the frequency domain so that later refinement of the image rendering process can be applied. Among the uses of such an algorithm, we can mention the search for an image in an image database and obtaining a certain fidelity of the result or the reconstruction of a specific image based on a sketch.
