Embodiment Construction
[0035] In order to facilitate those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] Such as figure 1 As shown, this embodiment provides a geometrically invariant object segmentation method based on sparse independent shape component representation, comprising the following steps:
[0037] A1: Perform logarithmic polar coordinate transformation on the training shape set;
[0038] A2: Extract independent shape components based on logarithmic polar transformation shape;
[0039] A3: Establishing a first mapped convex shape set based on extracting independent shape components;
[0040] A4: Building a second mapping convex sparse shape subset based on extracting independent shape components
[0041] A5: Establish a sparse independent shape component representation model;
[0042] A6: Establish a unified segmentati...
