Automatização do reconhecimento de células germinativas em imagens histológicas de ovários de peixes: estudo de caso de peixes encontrados no estado do Maranhão

Abstract

The state of Maranhão has significant fishing activity, making it essential to monitor the reproductive biology of fish for sustainable management. This work presents an automated approach for recognizing germ cells in histological images of fish ovaries, using digital image processing and supervised learning. The objective is to develop a tool that aids in the efficient analysis of gonads, contributing to knowledge in the field and better management of fishing resources. The methodology uses the Canny edge detection algorithm to segment cells and supervised learning techniques to classify them, overcoming the limitations of traditional manual methods. The results show gains in batch processing speed (50 images/minute) and precision (56% accuracy) with STERapp. The solution aims to increase the precision and reproducibility of analyses, positively impacting fishing sustainability in Maranhão and similar regions.
