摘要:
Techniques to determine a search range for a stereo based matching pyramid. A first disparity estimation value for a first level in a stereo based matching pyramid based on an image may be received. A search range for a second level may be determined using the first disparity estimation value. The search range based on a pyramid level of a second level may be increased. The search range may be increased based on a pyramid level of the second level. A second disparity estimation value may be selected from the search area for the second level. A depth map for the second level may be determined based on the second disparity estimation value. Other embodiments are described and claimed.

Systems and methods may provide for projection of a plurality of structured light patterns. In one example, the method may include generating a low-resolution pattern image utilizing a returned image, wherein the low-resolution pattern image is an approximation of an image that would have been generated utilizing a low-resolution pattern and generating a high-resolution pattern image utilizing a preprocessed returned image and a preprocessed low-resolution pattern image, wherein high-resolution pattern image is an approximation of an image that would have been generated utilizing a high-resolution pattern.

Systems and methods may include utilizing a structured light pattern that may be, among other things, decoded in the three directions (e.g., vertical, horizontal, and diagonal). In one example, the method may include detecting a first feature of a target image in a return image, designating a feature type of the first feature, and an index with the letter, wherein the index is associated with the pattern slide. The method may also include calculating a horizontal position in the pattern slide of the first feature, calculating a vertical position in the pattern slide of the first feature, and calculating a depth of the first feature.

A filtering system and method are disclosed, to perform simultaneous, de-noising, and details enhancement tasks of a video image. The efficient filtering system includes multiple filters, which operate on a portion of the video image that has been partitioned into multiple rings. Using the filtering system, complex mathematical operations are avoided.

An apparatus may include an image sensor that contains a multiplicity of pixel elements to detect one or more images and a processor circuit coupled to the image sensor. The apparatus may include a white balance module for execution on the processor circuit to receive, based upon a detected image of the one or more images, for a plurality of pixel elements of the multiplicity of pixel elements, three of more gray level values for a respective three or more color channels, to determine grayness likelihood functions for the respective three or more color channels, the three or more grayness likelihood functions comprising a proportional contribution to grey pixels of the detected image from one or more gray levels for each respective color channel, and to determine a white balance gain for two or more color channels based upon the determined grayness likelihood functions. Other embodiments are described and claimed.

An apparatus may include an emitter to project a low resolution optical pattern and a high resolution optical pattern having a finer resolution than the low resolution optical pattern and a sensor to detect a composite image, where the composite image comprises a low resolution optical reflection pattern comprising reflection of the projected low resolution optical pattern and a high resolution optical reflection pattern comprising a reflection of the projected high resolution optical pattern. The apparatus may also include logic to determine object depth in a first depth range and object depth in a second depth range based upon the detected composite image. Other embodiments are disclosed and claimed.
