This paper provides a sorting method for the identification of leguminous weed seeds by using clustering. The image processing methods are made use of threshold segmentation, smooth processing and edge detection etc, as well as the image processing algorithm is delivered. According to the stability and genetic characteristics describes in phytotaxonomy for leguminous weed seeds, the feature set includes...
This paper presents a contour-based approach to separate vertically attached traffic signs. The algorithm is based on using binary images which are generated by any color segmentation algorithm to represent objects which could be candidate traffic signs. Since all traffic signs are similar about their vertical axis, an improved cross-correlation algorithm is invoked to determine this similarity and...
We address two-dimensional shape-based classification, considering shapes described by arbitrary sets of unlabeled points, or landmarks. This is relevant in practice because, in many applications, the points describing the shapes come from automatic processes, e.g., edge detection, thus without labels. Rather than attempting to compute point correspondences (a quagmire, when dealing with nontrivial...
