摘要
A ghost detection method for high-dynamic range (HDR) image creation using multi-level median threshold bitmapping. At each of multiple levels, median threshold bitmaps (MTBs) are generated for each original low-dynamic range image. At each level, the MTBs of the multiple original images are compared to generate a ghost map for each original image which indicates the locations of ghost pixels in the original image. For each original image, the ghost maps generated at the multiple levels are combined to generate a combined ghost map. The multiple combined ghost maps can then be used in creating the HDR image, for example, by discarding pixels in an original image that are indicated by the corresponding combined ghost map as being a ghost pixel.
