Study on the recognition of the tactile image based on the sensor array

Tactile image collected by robotic paw tactile sensor array which uses semiconductor strain-gauge is analyzed in detail. Based on fuzzy clustering analysis, a scheme for recognizing tactile image is presented. To analyze the spatial knowledge of pixels' hue matrix and extract static features of image, a fuzzy similitude matrix is defined to describe the image's feature space. By introducing the fuzzy clustering analysis, a corresponding fuzzy equivalence matrix is obtained over the fuzzy similitude matrix by computing the transferred package. Under the biggest threshold, images are classified into two groups. The experiments show that the proposed approach is effective in image recognition.
