Alignment of objects is a predominant problem in part-based methods for visual object categorisation (VOC). These methods should learn the parts and their spatial variation, which is difficult for objects in arbitrary poses. A straightforward solution is to annotate images with a set of “object landmarks”, but due to laborious manual annotation, semi-supervised methods requiring only a set of images and class labels are preferred. Recent state-of-the-art VOC methods utilise various approaches… CONTINUE READING
