Desenvolvimento de um software para auxiliar o aprendizado de conceitos e aplicações abordados na disciplina de processamento digital de imagens.

Abstract

The work presents the development of a software for learning concepts of the discipline of digital image processing, bringing in assistant professors who teach these subjects and exemplifying in a practical way the techniques taught in the classroom, facilitating and contributing to the understanding by the student. . The techniques developed in the tool are the limits of where the image is binarized from a pixel intensity value, changing the brightness and contrast in the image with visualization of their respective histograms, applications of low pass filters with Gaussian and average filters that allow smoothing the image with noise like salt and pepper, applying high pass filters with edge detection by the Canny and Sobel operators, and finally the visualization of RGB and YCbCr color spaces and in grayscale. To validate the results and the functioning of the tool, a satisfaction survey was carried out with students who attended or attended the PDI subject using the average ranking calculation.
