Technology makes many of the tasks that were previously difficult to perform, nowadays can be solved, one of them is to be able to carry out studies on large tracts of land and at the same time be able to have a level of detail of them, through the study of the satellite images provided by the Earth observation satellites, these images are composed of a series of spectral bands that will depend on the type of satellite mission that was conceived and the optical instrument that is found as a payload, these images are represented by multidimensional arrays and large size, so computational high computation equipment is required to process the images, added to this requires specialized software that allows the visual interpretation of satellite images. To be able to work with satellite images you have many configurations, normally you work with the configuration of separate bands that consis...

When it is required to study the terrestrial coverage in large dimensions, the use of remote sensors is used, these provide us with information according to the type and coverage that they present in their configuration, these remote sensors present in general two types of images in accordance To the instrument they have on board, we first have the optical sensors that are on board the observation satellites, which provide information of the terrestrial coverage based on a representation of pixels that make up an image, they are characterized by the bands of colors Red, Green, Blue and in other bands such as short wave infrared and medium wave infrared among others that may have according to their purpose, these images present a level of detail according to their special resolution that can be metric and sub metric, one of the disadvantages of these sensors is that in the presence of clo...

Diabetes Mellitus is a metabolic disease characterized by the presence of elevated blood glucose levels. Diabetes itself causes other chronic complications, including an eye disease known as diabetic retinopathy. Nowadays, diabetic retinopathy is the most frequent cause of blindness among the active population of developed countries. The principles that produce this disease are not completely known and can not yet be prevented. However, there are effective treatments that delay their evolution as long as it is diagnosed with sufficient anticipation. The problem of diabetic retinopathy is that it is an asymptomatic disease and only defects appear in the vision at an advanced stage of the disease. So in the early stages of diabetic retinopathy is usually imperceptible, diabetic patients do not realize that they have the disease and do not undergo an eye examination. Sometimes the patient i...
