摘要： A method of detecting a face-like region of a colour image, comprises reducing the resolution of the colour image by averaging the saturation to form a reduced resolution image and searching for a region of the reduced resolution image. The searched region has, in a predetermined shape, a substantially uniform saturation which is substantially different from the saturation of the portion of the reduced resolution image surrounding the predetermined shape.

摘要： A method is provided for detecting a human face in an image, such as a sequence of images supplied by a video camera. The method comprises locating in each image a candidate face region and analyzing the candidate face region for a first characteristic indicative of a facial feature. The locating step may comprise detecting uniformity saturated regions of predetermined shape in a reduced resolution version of the image. The analyzing step may comprise selecting a signal color component, forming a vertical integral projection profile and detecting an omega shape in the profile characteristic of an eye region of a face.

摘要： View-dependent texture images and view-independent texture data for a 3D computer model are processed to compress each view-dependent texture image by subtracting the view-dependent data and view-independent data in a common 2D image space to generate a difference image, and compression encoding the difference image. The difference images, 3D computer model and view-independent texture data are transmitted to a second apparatus, where the difference data and view-independent texture data are recombined in a common 2D image space as part of the processing to render an image.

摘要： A texture map for texturing the polygon mesh of a 3D computer model during rendering is generated by defining a respective triangle within the texture map for each triangle in the polygon mesh to create a texture coordinate map, and allocating image data to each defined triangle. To generate the texture coordinate map, the triangles are defined so that the area of each triangle is dependent upon the content of texture data to be stored therein. More particularly, triangles required to store texture data with a relatively large amount of detail have a relatively large area and triangles which are required to store texture data with relatively little detail have a relatively small area. In this way, more area is allocated for the storage of detailed texture data, thereby reducing the amount of information which is lost from the texture data during the creation of a texture map.
摘要翻译：通过在多边形网格中为每个三角形定义纹理图中的相应三角形以产生纹理坐标图，并且将图像数据分配给每个定义的三角形，生成用于在渲染期间纹理化3D计算机模型的多边形网格的纹理图。为了生成纹理坐标图，定义三角形，使得每个三角形的面积取决于要存储在其中的纹理数据的内容。更具体地，存储具有相对大量细节的纹理数据所需的三角形具有相对较大的面积，并且存储相对较少细节的纹理数据所需的三角形具有相对小的面积。以这种方式，分配更多的区域用于存储详细的纹理数据，从而减少在纹理映射的创建期间从纹理数据丢失的信息量。

摘要： There is disclosed an apparatus and method for combining three or more texture maps 200–208 together to generate a single, combined texture map 220. The texture maps are repeatedly combined together in pairs, with each pair generating a larger texture map for subsequent combination with another texture map, until only one texture map remains containing all of the original texture maps.

摘要： This invention relates to a method for segmenting a pixellated image, comprising: (a) selecting at least one first region from a first reference image; (b) deriving from values of pixels of the at least one first region a first threshold such that a first predetermined proportion of the pixels have values on a first side of the first threshold; (c) forming a difference image as a difference between each pixel of the image and a corresponding pixel of an image of a non-occluded background; and (d) allocating each difference image pixel to at least one first type of region if the value of the difference image pixel is on the first side of the first threshold and the values of more than a first predetermined number of neighboring difference image pixels are on the first side of the first threshold. An apparatus for performing the foregoing method is disclosed.

摘要： A plurality of texture maps for a 3D computer model of an object are generated by processing images of the object, data defining the computer model, and data defining the relative positions and orientations of the images and computer model. A respective texture map is generated for the viewing position and direction of each image. Each texture map stores texture data for all parts of the computer model which are visible from the associated viewing position and direction and also texture data for all invisible parts of the computer model. Each texture map therefore stores texture data that can be used for rendering accurate images of the 3D computer model over a wide range of viewing positions and directions.

摘要： A texture map (188) for texturing a polygon mesh 3D computer model (150) during rendering is generated by defining a respective triangle within the texture map for each triangle in the polygon mesh to create a texture coordinate map (170), and allocating image data to each defined triangle. To generate the texture coordinate map, the triangles in the polygon mesh are processed to generate a plurality of lists, each list identifying adjacent triangles in the mesh having shapes which can be packed into strips (173-179) of the texture coordinate map without significant shape distortion. The triangle lists are then packed into the texture coordinate map strips. No padding is defined between triangles in the same list, only between triangles of different lists. Image data is allocated to each triangle.
