Example-based composite sketching of human portraits

Author Chen, Hong Liu, Ziqiang Xu, Yingqing Rose, Chuck Shum, Heung-Yeung Salesin, David
Abstract Creating a portrait in the style of a particular artistic tradition or a particular artist is a difficult problem. Elusive to codify algorithmically, the nebulous qualities which combine to form artwork are often well captured using example-based approaches. These methods place the artist in the process, often during system training, in the hope that their talents may be tapped.Example based methods do not make this problem easy, however. Examples are precious, so training sets are small, reducing the number of techniques which may be employed. We propose a system which combines two separate but similar subsystems, one for the face and another for the hair, each of which employs a global and a local model. Facial exaggeration to achieve the desired stylistic look is handled during the global face phase. Each subsystem uses a divide-and-conquer approach, but while the face subsystem decomposes into separable subproblems for the eyes, mouth, nose, etc., the hair needs to be subdivided in a relatively arbitrary way, making the hair subproblem decomposition an important step which must be handled carefully with a structured model and a detailed model.

About National Digital Library of India (NDLI)
NDLI logo

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.
