The purpose of the work presented in this paper is to derive a method for defect detection. For the first time in this context we adapt level set method to distinguish hollow regions in the metal pieces from the grinded surface. We compare this method with Canny edge enhancement and with a...

Contour detection is a hard, challenging, and of paramount importance problem in image processing. State-of-the-art algorithms are approaching human performance but usually entail complex and tailored image models and arduous training. Binary Partition Tree is a hierarchical region-based image model th...

It is feasible to establish the analogy between source localization in array processing [14, 15] and contour detection in image processing. Still in the field of contour-based segmentation methods, Aghajan et al. [16, 17] first proposed to transfer array processing methods to the field of ...
A creative algorithm is provided and fulfilled based on the binary-value image,which is obtained through preprocessing and edge detection,to fetch points by means of raster scan and to extract contours by border following. 文中提出并实现了一种新的按光栅顺序扫描取点,然后进行边界跟踪的轮廓线提取...
Contour detection : Lets see how to detect contours of particular color. Here I have done for blue color. Input image :- Following steps are needed : 1. Color space conversion : A good first step in many CV algorithms is to convert the image toHSV. HSV stands for Hue, Saturation and ...
Additionally, we introduce a new post-processing method that further suppresses texture edges. We use natural images with associated subjectively defined desired output contour and boundary maps to evaluate the performance of the proposed additional steps. In a contour detection task, the Canny operator...
An algorithm to realize fruit contour detection in color image is presented in this paper. At first, a color image is transformed into a grey-level image in OHTA color space, and segmented by constant threshold value; then the BLOB algorithm is utilized to erase noises in the image; a spli...
An 'Initial Contour' refers to the starting boundary or shape used in image processing algorithms such as active contours or snakes for object detection and segmentation. AI generated definition based on: Image and Vision Computing, 2008 About this pageAdd to MendeleySet alert ...
