Bounding Fundamental Performance of Feature-Based Object Recognition

چکیده

Performance prediction is a crucial step for transforming the eld of object recognition from an art to a science. In this paper, we address this problem in the context of a vote-based approach for object recognition using 2-D point features. A method is presented for predicting tight lower and upper bounds on fundamental performance of the selected recognition approach. Performance bounds are predicted by considering data-distortion factors, which are uncertainty, occlusion and clutter, in addition to model structural similarity. Given a statistical model of data uncertainty, the structural similarity between every pair of model objects is computed as a function of the relative transformation between them. Model-similarity information is then used along with statistical data-distortion models to predict bounds on the probability of correct recognition. Validity of the method is experimentally demonstrated using MSTAR public SAR data.

3D Models Recognition in Fourier Domain Using Compression of the Spherical Mesh up to the Models Surface

Representing 3D models in diverse fields have automatically paved the way of storing, indexing, classifying, and retrieving 3D objects. Classification and retrieval of 3D models demand that the 3D models represent in a way to capture the local and global shape specifications of the object. This requires establishing a 3D descriptor or signature that summarizes the pivotal shape properties of th...
