...In traditional systems like SIFT[61] or HOG[62] or Deep Pose[58] for human pose recognition much work is devoted to engineering the system to produce the vector representation that is sensitive to class (e....

...Fully convolutional networks adapted from contemporary classification networks such as AlexNet[10], www.ijcsit.com 2207 GoogleNet[12] and VGG net[11] achieve state-of-the-art segmentation of PASCAL VOC (20% relative improvement to 62.2% mean IU on 2012), NYUDv2, and SIFT Flow, while inference takes less than one fifth of a second for a typical image....

...Researchers at Stanford University suggested an improvement to the common approaches in visual recognition which relied on SIFT[39] and HOG[40] using Independent Subspace Analysis (ISA) algorithm which is an extension of Independent Component Analysis (ICA) which is well-known for its use in natural image statistics[41]....

...In traditional systems like SIFT[61] or HOG[62] or Deep Pose[58] for human pose recognition much work is devoted to engineering the system to produce the vector representation that is sensitive to class (e.g. head, hands, torso) while remaining invariant to the various nuisance factors (lighting, viewpoint, scale, etc.) However, the non-rigid structure of the body, the necessity for precision (deep recognition systems often throw away precise location information through pooling), and the complex, multimodal nature of pose contribute to the problems of the traditional networks....

...This allows for the use of more distinctive image descriptors than the rotation-invariant ones used by Schmid and Mohr, and the descriptor is further modified to improve its stability to changes in affine projection and illumination....

...For the object recognition problem, Schmid & Mohr [19] also used the Harris corner detector to identify interest points, and then created a local image descriptor at each interest point from an orientation-invariant vector of derivative-of-Gaussian image measurements....
