| Abstract | This paper proposes an object oriented face detection method using range and color information. Objects are segmented from the background using the stereo disparity histogram that represents the range information of the objects. A matching pixel count (MPC) disparity measure is introduced to enhance the matching accuracy, and removes the effect of unexpected noise in the boundary region. For the high-performance implementation of the MPC disparity histogram, redundancy operations inherent to the area-based search operation are removed. To detect facial regions among segmented objects, a skin-color transform technique is used with the generalized face color distribution (GFCD) modeled by a 2D Gaussian function in a normalized color space. Using GFCD, the input color image can be transformed into a gray-level image enhancing only facial color components. To detect facial information only in the defined range, both results from range segmentation and color transforms are combined effectively. The experimental results show that the proposed algorithm works well in various environments with multiple human objects. Moreover, the processing time for a test image is not exceeding 2 seconds in general purpose workstations. The range information of the objects can be useful in MPEG-4 where natural and synthetic images can be mixed and synthesized. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
