A gesture spotting detection method and apparatus employ a shoulder-line algorithm. The shoulder-line detecting method recognizes a GSD calling gesture that occurs in a shoulder-line, head or higher part in a remote distance or a short distance, although a user does not have a fixed posture. In the method, an image of people is received, and skin information of a person in the image is detected to detect a face area. Then, the cloth color information of the person is modeled from the inputted image to detect a cloth area. An external space is defined from the image based on the body space area, and an edge is extracted from the image based on the body space and the external space. Then, shoulder-line information is acquired based on an energy function obtained based on the body space, the external space, and the edge.

The systems and methods described herein may allow diffusion curve images to be displayed by a variety of applications without requiring specialized graphics hardware to render the images. The system may provide mechanisms to convert a diffusion curve representation to an alternate representation in a scalable, portable format. The conversion may include a tessellation operation, and may produce a mesh of shapes (e.g., triangles) for which diffusible attribute values (e.g. color and blur) are assigned to each node. Tessellating an image may include generating a piecewise linear approximation of the diffusion curves and triangulating the image to generate the mesh. Color values for each channel may be assigned by solving a sparse linear system in the triangle domain. The alternate representation may be displayed by another application using various interpolation techniques. The alternate representation may be resolution-independent and compact, as compared to other representations used to display diffusion curve images.

The invention provides a real-time three-dimensional image illumination simulation method based on graphics processing units. The method orderly comprises the following steps that: (1) to-be-processed texture in three-dimensional image data is saved in a graphics processing unit; (2) the graphics processing unit calculates the illumination amount of texture data points according to an illumination model arranged in the graphics processing unit; and (3) the graphics processing unit mixes the illumination amount of the texture data points with a data value.

By rendering the post-conversion volume data, the large elasticity values of areas of noteworthy hardness are integrated and 3-dimensional elasticity images are generated.

A “composite signal generator” automatically combines two or more copies of a signal to produce a composite that is better than the individual copies. For example, given two or more input images of a scene captured from approximately the same viewpoint, the composite signal generator automatically produces a composite image having reduced or eliminated areas of occlusion with respect to any occlusions existing in the input images. First, the input images are registered using conventional image registration techniques. Differences between the registered images are then used to identify regions of potential occlusion in one or more of the images. A determination of which image is actually occluded is made by identifying which image has a larger discontinuity along a border of the potentially occluded regions. A composite image is then created by choosing one image and mosaicing parts from the other images where it is occluded and they are not.
