Claim:
1. A system for computed tomography (CT) viewpoint recognition in CT images comprising: a feature engine comprising a global binary pattern feature calculation unit and at least one image feature calculation unit, said global binary pattern feature calculation unit: (i) preprocessing said CT images with histogram equalization to maximize contrast in one or more pre-determined regions, (ii) extracting connected components from said preprocessed CT images, and (iii) forming a feature vector based on said extracted connected components; a cognitive engine comprising: (i) a plurality of classifiers, one for each of said global binary calculation unit, and (ii) at least one image feature calculation unit; and a voting unit picking a class label for each of the CT images based on a majority voting scheme determining the most frequently returned label among said classifiers.
