Abstract: A new recognition method using two characteristics for image texture is proposed.In this approach，image texture is represented as a sequence of codes based on encoded contour lines for its texture patterns.By using suffix array，the characters of the texture are extracted from the chain strings based on MDL criterion，and its repeated frequency is calculated by flexible pattern matching algorithms in strings.Finally，different textures are recognized by the character strings and its frequency based on Bayesian clustering.Experimental results by using ore material photos demonstrate the effectiveness of the approach.
