摘要： Various implementations relate to improving depth maps. This may be done, for example, by identifying bad depth values and modifying those values. The values may represent, for example, holes and/or noise. According to a general aspect, a segmentation is determined based on an intensity image. The intensity image is associated with a corresponding depth image that includes depth values for corresponding locations in the intensity image. The segmentation is applied to the depth image to segment the depth image into multiple regions. A depth value is modified in the depth image based on the segmentation. A two-stage iterative procedure may be used to improve the segmentation and then modify bad depth values in the improved segmentation, and iterating until a desired level of smoothness is achieved. Both stages may be based, for example, on average depth values in a segment.

The system and method of the present disclosure provide for acquiring a first image and a second image from a scene, estimating the disparity of at least one point in the first image with at least one corresponding point in the second image, and minimizing the estimated disparity using a belief propagation function, e.g., a global optimization function, wherein the belief propagation function is initialized with a result of a deterministic matching function, e.g., dynamic programming, applied to the first and second image to speed up the belief propagation function. The system and method further generates a disparity map from the estimated disparity and converts the disparity map into a depth map.

摘要： A system and method for extracting depth information from at least two images employing region-based filtering for reducing artifacts are provided. The present disclosure provides a post-processing algorithm or function for reducing the artifacts generated by scanline Dynamic Programming (DP) or other similar methods. The system and method provides for acquiring a first image and a second image from a scene, estimating the disparity of at least one point in the first image with at least one corresponding point in the second image to generate a disparity map, segmenting at least one of the first or second images into at least one region, and filtering the disparity map based on the segmented regions. Furthermore, anisotropic filters are employed, which have a great smoothing effect along the vertical direction than that of the horizontal direction, and therefore, reduce stripe artifacts without significantly blurring the depth boundaries.
