Computer Vision: Visual Extent of an Object
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2013, Vol 14, Issue 4
Abstract
The visual extent of an object reaches beyond the object itself. It is reflected in image retrieval techniques which combine statistics from the whole image in order to identify the image within. Nevertheless, it is still unclear to what degree and how this visual extent of an object affects the classification performance.Here we analyze the visual extent of an object on the Pascal VOC dataset using bag of words implementation with SIFT Descriptors. Our analysis is performed from two angles: (a) Not knowing the object location, we determine where in the image the support for object classification resides (normal situation) and (b) Assuming that the object location is known, we evaluate he relative potential of the object and its surround, and of the object border and object interior (ideal situation).
