摘要： A depth image of a scene may be received, observed, or captured by a device. The depth image may then be analyzed to determine whether the depth image includes a human target. For example, the depth image may include one or more targets including a human target and non-human targets. Each of the targets may be flood filled and compared to a pattern to determine whether the target may be a human target. If one or more of the targets in the depth image includes a human target, the human target may be scanned. A skeletal model of the human target may then be generated based on the scan.

摘要： A method of compressing a digital image defined by a plurality of pixel values in each of one or more channels includes adjusting each pixel value in each of the one or more channels by an average pixel value for that channel. The method further includes splitting each adjusted channel into one or more image blocks, and converting each image block into a frequency block that is a frequency-domain representation of that image block.

摘要： A depth image of a scene may be received, observed, or captured by a device. A human target in the depth image may then be scanned for one or more body parts such as shoulders, hips, knees, or the like. A tilt angle may then be calculated based on the body parts. For example, a first portion of pixels associated with an upper body part such as the shoulders and a second portion of pixels associated with a lower body part such as a midpoint between the hips and knees may be selected. The tilt angle may then be calculated using the first and second portions of pixels.

摘要： Techniques for pre-processing image blocks containing texture are disclosed herein which reduce memory requirements without degradation of quality. This is accomplished by determining the level of texture in each pixel block of the image and then performing a compression algorithm on such pixel block. Various methods are available to determine the texture level, including identifying the luminescence variation or difference within the pixel block. Depending on the amount of texture level contained within each pixel block, pre-processing may involve assigning the pixel block a single color or replacing the pixel block with an interpolated pixel block. Pre-processing on the pixel block may not be performed when the texture level therein is determined to be at a predetermined amount or level. Additional techniques are also disclosed herein which involve full processing of an image block.
摘要翻译：本文公开了用于预处理包含纹理的图像块的技术，其中减少了存储器需求而不降低质量。这是通过确定图像的每个像素块中的纹理水平，然后在这样的像素块上执行压缩算法来实现的。可以使用各种方法来确定纹理水平，包括识别像素块内的发光变化或差异。根据包含在每个像素块内的纹理水平的量，预处理可以包括将像素块分配给单一颜色或者用内插像素块替换像素块。当其中的纹理水平被确定为预定量或水平时，可能不执行对像素块的预处理。本文还公开了涉及图像块的完全处理的附加技术。

摘要： A method of tracking a target includes receiving an observed depth image of the target from a source and analyzing the observed depth image with a prior-trained collection of known poses to find an exemplar pose that represents an observed pose of the target. The method further includes rasterizing a model of the target into a synthesized depth image having a rasterized pose and adjusting the rasterized pose of the model into a model-fitting pose based, at least in part, on differences between the observed depth image and the synthesized depth image. Either the exemplar pose or the model-fitting pose is then selected to represent the target.

One or more pixels of the depth image may be analyzed to determine whether the pixels in the depth image are associated with the environment of the depth image. The one or more pixels associated with the environment may then be discarded to isolate the human target and the depth image with the isolated human target may be processed.

摘要： A system and method are disclosed for calibrating a depth camera in a natural user interface. The system in general obtains an objective measurement of true distance between a capture device and one or more objects in a scene. The system then compares the true depth measurement to the depth measurement provided by the depth camera at one or more points and determines an error function describing an error in the depth camera measurement. The depth camera may then be recalibrated to correct for the error. The objective measurement of distance to one or more objects in a scene may be accomplished by a variety of systems and methods.
