Resumo

The mosquito Aedes aegypti can transmit some diseases, which makes the study of the proliferation of this vector a necessary task. With the use of traps made in the laboratory, called ovitraps, it is possible to map egg deposition in a community. Through a camera, coupled with a magnifying glass are acquired images containing the elements (eggs) to be counted. First, the goal is to find pixels with a similar color to mosquito eggs, for that, we take advantage of the slice color method. From these already worked images, a process of transfer learning with a convolutional neural network (CNN) is carried out. The intention is to separate which elements are actually eggs from the others. In 10\% of the test images, the count performed by the model in relation to the actual number of eggs was considered to be weakly correlated, this occurs in images that have a high density of eggs or appear black elements that resemble mosquito eggs, but they are not. For the remaining 90\% of test images, the counting was considered to be perfectly correlated.
