Fig. 2From: Detection of Aβ plaque deposition in MR images based on pixel feature selection and class information in image levelFlowchart of this detection idea. The process consists of four main steps, including segmentation of brain tissue with MRIcro, pixel feature extraction, feature selection with CAGA or PCA, and classifier testing; marking of brain MR images is based on the coordinate information of the pixel featuresBack to article page
