It is intractable problem to segment the fluorescence image of T-cells with different sizes, irregular shape, and severe overlapping by conventional marker-based watershed segmentation. In this paper, Adaptive Marker-controlled Watershed method (AMWS) will be proposed. The Otsu strategy firstly is performed twice in a row to capture as many T-cells as possible. Then based on T-cells' roundish shape,...
In older to measure the cereal grain size rapidly and objectively, a measurement method based on digital image processing technology was proposed. Firstly, the grain images acquired by a scanner were preprocessed by using the methods of image enhancement and morphological reconstruction. Then 2D Otsu was used to segment the image. Finally, through image analysis technology the grain size parameters...
By analyzing the characteristics of off-road images, a new and computationally efficient algorithm of road segmentation and road type identification for autonomous land vehicle (ALV) navigation system based on the proposed new-type histogram calculation was established. The new-type histogram is a new image, not a curve. It is also directional. It makes a statistic of the pixels under some special...
Characteristics of surface defects of hot rolled steel plates were analyzed, and an algorithm for detection of hot rolled steel plates was developed. Based on undecimated wavelet transform and mathematical morphology, the algorithm can solve the problem of false alarms by scales and water marks. Positions of defects were determined by modular maximum of inter-scale correlation of wavelet coefficient...
