Image stitching are ideally suited for applications such as image stabilization, summarization, and the creation of panoramic mosaics. This paper proposes a approach to stitch images fast and with high quality.Image alignment algorithms can discover the correspondence relationships among images with varying degrees of overlap. In this process, they uses SIFT to look for the trait points, and uses...
We propose a robust background subtraction method for multi-view images, which is essential for realizing free viewpoint video where an accurate 3D model is required. Most of the conventional methods determine background using only visual information from a single camera image, and the precise silhouette cannot be obtained. Our method employs an approach of integrating multi-view images taken by multiple...
Rapid calibration of multi-camera systems using planar targets is typically impractical. Here we report a non-planar target for rapid calibration of inward-looking visual sensor networks (VSNs), designed using a novel VSN simulator and verified experimentally. The target consists of a large central sphere, surrounded by several smaller, rigidly mounted spheres. Rotation about an axis through the center...
This work aims at investigating the influence of luminance information and environment illumination on skin classification. We explore Bayesian approaches to perform automatic classification of human skin pixels on digital images, using color features as input. Two probabilistic skin color models were built on different color spaces (RGB, normalized RG, HSI, HS, YCbCr and CbCr) and tested in a task...
