WMS (Web Map Service) is the standard that is formulated by OGC (Open Geospatial Consortium), and TMS (Tile Map Service) is the specification that is formulated by OSGeo (Open Source Geospatial Foundation), the objective of both are to realize the sharing and interoperability of geographical information, using those standards, we can build the network that is composed of distributed map servers, the...
Real-time hand and face localization is a challenging problem in many application scenarios such as face and gesture recognition in computer vision and robotics. This paper proposes a robust method which can locate multiple faces and hands simultaneously under the changing environment of light illumination and complex background in real time by using skin-color detection and K-means in conjunction...
There are many biometric features in the hand images captured by digital camera, but few studies are done to extract fingerprint image from it. This paper presents some fingerprint image preprocessing approaches based on a whole-hand image captured by digital camera. The preprocessing methods include key point location, finger image segmentation and fingerprint region extraction. Firstly, the key...
The paper presents a new interactive local color transformation method base on GrowCut image segmentation algorithm. The method improves Maslennikova et al's CIM based color transformation algorithm by using coupled map lattices (CML). An intuitive and easy user interface is also supported. User just needs to draft some trails both in reference and target image to make the local color matched. The...
This paper presents a new face recognition method based on the analysis of local features. Firstly, we can get the images of magnitude by means of analyzing face images with the Gabor wavelets. Secondly, the magnitude images are divided into blocks, then principle components analysis (PCA) could be directly used to all the blocks to construct the feature space. Finally, all the blocks of images are...
A research on stylized rendering of Yunnan heavy color painting is attempted in this paper. First, plentiful Yunnan heavy color paintings are collected. Texture patches are extracted from these paintings and a texture library is constructed. The technique of edge detection in image space is used to extract the outline from photographic image and produce an outline drawing. The photographic image is...
In this paper, a novel method is proposed to detect faces based on PCNN time signature and skin color segmentation, in which no training is needed. A test image is first divided into overlapped blocks and extracted PCNN time signature as the detection features, which a two-dimensional image is projected to a one-dimensional feature space. The test blocks are matched to a face template, which can be...
A scalar median filter algorithm for color image based on the rotation of color space is presented in this paper. It converts the vector median filter to simpler scalar median filters by rotating color space. The rotation of color space can make the majority noise pixels satisfying scalar median filter conditions at each scalar and being filtered. This method is iterative, and the rotation matrix...
