Descripción: “...S-CIELAB involves a series of smoothing spatial filters in the opponent color space to approximate the contrast sensitivity functions of the human vision system. The filters are linear combinations of Gaussian masks. ...”

Descripción: “...It was found that the humidity control is possible by increasing the residence time of the grain, allowing the air inlet/outlet flow which induces an ideal temperature for the product. Several non-linear effects of the thermal systems are detected, being necessary approximations in different operating ranges, mitigating those conditions that generate cost overruns to the producer, presenting a system based on a transfer function, to which several tests are performed to know the appropriate point of operation on a real scale, evidenced in the work carried out by a local company in the improvement of its silos for the ecological benefit of cocoa. ...”
