Abstract: This paper proposes to closely combine computer machine vision, image processing and image analysis technologies, which is used for analyzing image texture features. By summarizing the existing research results, image texture features, which are extracted by different algorithm ideas such as regionalization, marginalization and mathematical transformation, are studied and analyzed. An image texture feature processing scheme whose computational cost tends to be processed in real time is proposed. More refined algorithms of texture classification, texture segmentation, texture splicing and texture registration are studied in this scheme, which can achieve the accuracy and good scalability of image texture feature extraction. This scheme also achieve timeliness, accuracy and efficiency of subsequent essential applications, such as classification, segmentation, splicing and registration, etc..

Keywords: analysis of image texture features; computer machine vision; image processing
