In this paper problem of accurate segmentation of images presenting melted specimens of metal is considered. Firstly the theory of thermal phenomena influence on recorded images is explained. A review of most popular edge-based segmentation methods is provided. Results of applying drop shape analysis algorithm to segmented images are presented, analyzed and discussed.
In this paper problem of accurate edge detection in images of heat emitting objects is considered. Firstly the theory of edge detection is surveyed. A review of existing techniques for edge detection is provided. Especially methods based on analysis of image derivatives are regarded. Results of applying the considered methods to images of melted specimens of metals and alloys are presented, analyzed...
