Title:
ジョイントバイラテラルフィルタの効率的な実現
Document Type and Number:
Japanese Patent JP7094299
Kind Code:
B2
Abstract:
An integrated circuit and computer-implemented method are provided for estimating a depth map from an image, using a joint bilateral filter. For that purpose, image data of an image is accessed as well as depth data from a depth map profile. A joint bilateral filter is then applied to the depth map profile using the image data as a range term in the joint bilateral filter, thereby obtaining an image-adapted depth map as output. The applying of the joint bilateral filter comprises initializing a sum-of-weights volume and a sum-of-weighted-depth volume as respective data structures in a memory, performing a splatting operation to fill said volumes, performing a slicing operation to obtain an image-adapted depth volume, and performing an interpolation operation to obtain an image-adapted depth value for each pixel in the image.
