Abstract:
A structure estimation module comprising:a. means to receive an image input; b. means to receive an application domain structure input; c. a preprocessing module that receives the image input having a pre-processed image output; d. a distributed estimation module that receives the pre-processed image and application domain structure inputs having an estimated structure output wherein the distributed estimation module comprises i. a sub-region generation module having a sub-region output; ii. a robust structure-guided estimation module that receives the sub-region output and a box caliper input having a feature parameter output wherein the box caliper robust structure-guided estimation module comprises: (a) means to perform row-wise robust feature direction estimation and weight adjustment having an adjusted weight output; (b) means to perform column-wise robust feature direction estimation and weight adjustment having an adjusted weight output; (c) means to perform overall robust feature direction estimation and weight adjustment having a feature direction estimation result.
