PoseShop: Human Image Database Construction and Personalized Content Synthesis
Found in: IEEE Transactions on Visualization and Computer Graphics
By Tao Chen, Ping Tan, Li-Qian Ma, Ming-Ming Cheng,A. Shamir, Shi-Min Hu
Issue Date:May 2013
pp. 824-837
We present PoseShop - a pipeline to construct segmented human image database with minimal manual intervention. By downloading, analyzing, and filtering massive amounts of human images from the Internet, we achieve a database which contains 400 thousands hu...
 
Change Blindness Images
Found in: IEEE Transactions on Visualization and Computer Graphics
By Li-Qian Ma, Kun Xu, Tien-Tsin Wong, Bi-Ye Jiang, Shi-Min Hu
Issue Date:November 2013
pp. 1808-1819
Change blindness refers to human inability to recognize large visual changes between images. In this paper, we present the first computational model of change blindness to quantify the degree of blindness between an image pair. It comprises a novel context...
 
A practical algorithm for rendering interreflections with all-frequency BRDFs
Found in: ACM Transactions on Graphics (TOG)
By Kun Xu, Li-Qian Ma, Rui Wang, Shi-Min Hu, Yan-Pei Cao, Zhao Dong
Issue Date:January 2014
pp. 1-16
Algorithms for rendering interreflection (or indirect illumination) effects often make assumptions about the frequency range of the materials' reflectance properties. For example, methods based on Virtual Point Lights (VPLs) perform well for diffuse and se...
     
Inverse image editing: recovering a semantic editing history from a before-and-after image pair
Found in: ACM Transactions on Graphics (TOG)
By Bin Liu, Jue Wang, Kun Xu, Bi-Ye Jiang, Li-Qian Ma, Shi-Min Hu
Issue Date:November 2013
pp. 1-11
We study the problem of inverse image editing, which recovers a semantically-meaningful editing history from a source image and an edited copy. Our approach supports a wide range of commonly-used editing operations such as cropping, object insertion and re...
     
Interactive hair rendering and appearance editing under environment lighting
Found in: ACM Transactions on Graphics (TOG)
By Bo Ren, Kun Xu, Li-Qian Ma, Rui Wang, Shi-Min Hu
Issue Date:December 2011
pp. 1-15
We present an interactive algorithm for hair rendering and appearance editing under complex environment lighting represented as spherical radial basis functions (SRBFs). Our main contribution is to derive a compact 1D circular Gaussian representation that ...
