In this sense, the area of computer vision has had developments to generate non-destructive tools in agriculture, however, there are few works that relate mango and anthracnose by means of CVS and much less for early detection of this disease. In the present work, five methods based on machine vision were developed: Threshold-RGB, RGB-LDA, Threshold-UV, LDA-UV and 3D method, with the purpose of early detection of anthracnose in mango fruits. Results on 30 mangoes indicate that the Threshold-UV and LDA-UV methods can detect the disease 2 days before an expert can do so, according to the severity scale used. This is because UV-A illumination reveals areas of disease that cannot be seen in visible light. The Threshold-RGB and RGB-LDA methods have a performance similar to that of the human eye, since they have the same information. On the other hand, the 3D method does not have a good performance in the detection of the disease, for the test performed, the intersection over junction (IoU) is 47%, which indicates that it is not a good method to determine the disease. Finally, a comparison of the 5 proposed methods using the IoU metric on the same handle is performed, the result of the best segmentations are of the RGB Threshold and LDA-UV methods with values of 0.87 and 0.84, respectively. The lowest performance was 3D segmentation with an average IoU of 0.56. The methods were taken to the field, with unfavorable results, due to uncontrolled factors such as illumination and wind, in addition to the fact that the mangoes evaluated did not show any symptoms of the disease.(Texto tomado de la fuente)La antracnosis es la principal enfermedad que afecta los frutos de mango llegando a generar hasta el 100% de perdidas en los casos más extremos, de ahí la importancia de controlar la enfermedad en mango para no llegar a tales extremos. En este sentido, el área de visión por computadora ha tenido desarrollos para generar herramientas no destructivas en agricultura, sin embargo, son pocos los trabajos que relacionan el mango y la antracnosis por medio de CVS y mucho menos para detectar de forma temprana esta enfermedad. En el presente trabajo se desarrollaron cinco métodos basados en visión de máquina: Umbral-RGB, RGB-LDA, Umbral-UV, LDA-UV y método 3D, con el propósito de detectar la antracnosis de forma temprana en frutos de mango. Los resultados sobre 30 mangos indican que los métodos Umbral-UV y LDA-UV pueden detectar la enfermedad 2 días antes que un experto lo pueda realizar, de acuerdo con la escala de severidad empleada. Lo anterior debido a que la iluminación de luz UV-A que se realiza devela zonas de la enfermedad que en la luz visible no se pueden ver. Los métodos Umbral-RGB y RGB-LDA tienen un desempeño similar al realizado por el ojo humano, esto dado que tienen la misma información. Por otro, lado el método 3D no tiene un buen desempeño en la detección de la enfermedad, para la prueba realizada, la intersección sobre unión (IoU), es de 47 %, lo que indica que no es un buen método para determinar la enfermedad. Finalmente se realiza una comparación de los 5 métodos propuestos empleando la métrica IoU sobre un mismo mango, el resultado de las mejores segmentaciones son de los métodos Umbral RGB y LDA-UV con valores de 0.87 y 0.84, respectivamente. El menor desempeño fue la segmentación 3D con un promedio de IoU de 0.56. Los métodos fueron llevados a campo, con resultados poco favorables, por factores no controlados como la iluminación y el viento, además que los mangos evaluados no debelaban ningún síntoma de la enfermedad.
