Inputs checking using … WebJan 7, 2024 · In this paper, we use two commonly used matrices, namely, the gray level-gradient cooccurrence matrix (GGCM; Jiguang, 1984) and the gray-level run length matrix (GLRLM; Galloway, 1975 ), to extract texture features and then introduce texture features into dynamic PET reconstruction. The GGCM reflects the two most basic …

WebJul 10, 2015 · The GLRLM is a matrix which attempts to quantify runs of the same grey level in the image. The GLRLM is set up slightly differently than the GLCM; instead of having grey levels along the abscissa of the table the GLRLM has run lengths. As with the GLCM, an angle is required (one of “0”, “45”, “90”, or “135”). Below is an example ... WebNov 2, 2024 · Radiomics image analysis toolbox for 2D and 3D radiological images.
