Fig. 5From: Detection of Aβ plaque deposition in MR images based on pixel feature selection and class information in image levelFlowchart of elastic mapping based on the optimal feature subset. “0” indicates that the feature of the location is not selected; “1” indicates that the feature of the location is selected. Feature subsets were obtained by binary coding; m is the total number of samples. By all of the feature subsets, the optimal feature subset is obtained. Pixel vectors with different dimensions were obtained using elastic mapping from the optimal feature vectors. By the pixel vectors, the corresponding pixels in the brain images can be found and marked, thus providing information about Aβ plaque depositionBack to article page
