Redundant pixel mitigation

摘要

Among other things, one or more techniques and/or systems are provided for mitigating redundant pixel texture contribution for texturing a geometry. That is, the geometry may represent a multidimensional surface of a scene, such as a city. The geometry may be textured using one or more texture images (e.g., an image comprising color values and/or depth values) depicting the scene from various view directions (e.g., a top-down view, an oblique view, etc.). Because more than one texture image may contribute to texturing a pixel of the geometry (e.g., due to overlapping views of the scene), redundant pixel texture contribution may arise. Accordingly, a redundant textured pixel within a texture image may be knocked out (e.g., in-painted) from the texture image to generate a modified texture image that may be relatively efficient to store and/or stream to a client due to enhanced compression of the modified texture image.

1. A method for mitigating redundant pixel texture contribution for texturing a geometry, comprising:
applying a first texture image to a geometry to identify a first pixel texture contribution by the first texture image to the geometry, the first pixel texture contribution identifying a textured geometry pixel within the geometry that is textured by the first texture image, the first texture image depicting a scene, represented by the geometry, according to a first view direction; identifying a redundant textured pixel provided by a second texture image for the geometry based upon the redundant textured pixel corresponding to the textured geometry pixel, the second texture image depicting the scene according to a second view direction; knocking out the redundant textured pixel from the second texture image to generate a modified second texture image and mitigate redundant pixel texture contribution; pre-processing the modified second texture image to generate a pre-processed second texture image; and streaming the geometry, the first texture image, and the pre-processed second texture image to a client for texturing of the geometry using at least some of the first texture image and at least some of the pre-processed second texture image, at least some of the method implemented via a processing unit.
