While several of the characteristics of human sight haves been elucidated mainly in a the fields of medicine and psychology, many remain unclear. In particular, the details of the pro-sight mechanism are hoped to elucidate the cause of the optical illusion. The following sentence was hard to understand, so I took a guess. Please use my version as a model to rewrite your sentence. We carried out multi-scale analysis of the Hellmann grid image by Using wavelet transforms. We used the results of physiological research on neurons to find channels in which there is frequency selectivity. The concept of the Hellmann grid is that there is an illusion of dark spots in the intersection of white lines. The illusion in the Hellmann grid image is caused by 'side restraint' and creates a high black-and-white contrast. Therefore, a model showing a dark spot is explained by side restraint.
