  21. 21. Results and Conclusions Time image processing with Matlab was 396.4 msThe prototype meets the 15.75% of all images processedby the human eye (16 frames per second). 21
  22. 22. ConclusionsThe components used comply with the objectives proposedof stimulation.The prototype is economical.With sensory substitution can replace the functions ofthe sense of sight with the sense of touch. 22
  23. 23. Future outlook.Stimulating array of pins with a resolution of 256 x 256 pixels.Processing and reduction of the image should be automatic. 23
  24. 24. Future outlook.Using C language for image processing software decreasingcosts. Try other more complex shapes. 24
