The present work had been special related with the fact of those people with hearing problems that need visual signs (in this case, signs that belong to the “Lengua de Signos Peruana” LSP) to communicate with other people; that is why from this fact I presented a study about the design of a technic for the recognition of signs based in the “Lengua de Signos Peruana” (LSP) using the Blurred Shape Model (BSM) descriptor. For the design of this technic, we used image processing algorithms in every phase of the technic, which were: pre-process, segmentation, description and recognition, which together generated the technic to design. To determine what algorithms we had to use in each phase, first of all, they had to analyze according to varied evaluation criteria, which they went according the needs of this work and determined their selection and utilization, once they had determined...
