Research on footwear impression evidence has been gaining increasing importance in forensic science. Given a footwear impression at a crime scene, a key task is to find the closest match in a local/national database so as to determine footwear brand and model. This process is made faster if database prints are grouped into clusters of similar patterns. We describe a clustering approach based on common...
This paper presents an novel technique that employs both the color and edge direction features for Content-Based Image Retrieval (CBIR). In this method, a given image is first divided into sub-block which has the same size and then the color and edge direction features of each sub-block can be extracted. Next, it constructs a codebook of color feature using clustering algorithm and then each sub-block...
The problem of automatic defect recognition and classification for vision systems development is addressed. The main objectives of such systems are defect recognition and classification based on known features. The classification function is designed using cluster analysis. Two stages approach is proposed. On the first offline stage of classification a teaching process has been employed. On the second...
