Abstract
A method for generating a target perspective model referenced for depth map generation includes at least following steps: receiving a first input image; utilizing a region-based analysis unit for analyzing a plurality of regions in the first input image to extract image characteristics of the regions; and determining the target perspective model according to at least the image characteristics. Another method for generating a target perspective model referenced for depth map generation includes: receiving a first input image; determining a first perspective model in response to the first input image; and utilizing a perspective model generation unit for generating the target perspective model by a weighted sum of the first perspective model and at least one second perspective model.
