Arthritic Hand-Finger Movement Similarity Measurements: Tolerance Near Set Approach
Figure 6
Figure showing preprocesing required to create tolerance classes and calculate tNM. (a) Original image. (b) Segmented image. (c) Hand segment only. (d) Cropped image to eliminate useless background. (e) Final image used to obtain tolerance classes. Each square represents an object where the colour (except black) represents the average orientation of a line segment within that subimage.
