Image Quality Analysis Using GLCM
Gray level co-occurrence matrix has proven to be a powerful basis for use in texture classification. Various textural parameters calculated from the gray level co-occurrence matrix help understand the details about the overall image content. The aim of this research is to investigate the use of the …

Quantitative Texture Analysis and Automated Segmentation of Patellar Tendon Sonographic Images on Collegiate Athletes
Patellar tendinopathy, a common cause of anterior knee pain, is primarily due to degenerative changes in the patellar tendon resulting from repetitive stress. While the tendon itself is the primary focus, damage can also manifest in surrounding tissues, such as the subcutaneous tissue and the fat …

Computer vision and texture analysis for characterization of X-ray images of rocks
X-ray micro-computed tomography (micro-CT) has provided us digital twins of physical rocks. Digital twins are raw grayscale micro-CT images that contain information regarding rock-microstructure. These raw micro-CT images are then transformed into their segmented counterparts, which attempt to …
