When computing optical flow with region-based matching, very few of them can be reliably obtained, especially for the high-contrast areas or those with little texture. Instead of using a single pixel from the reference frame, non-deterministic motion utilizes multiple pixels within a neighborhood to represent the corresponding pixel in the current frame. Although remarkable improvement has been made...
This paper presents a novel approach for depth recovery based on bifocus imaging. The imaging system with bifocus lenses may focus at different focal lengths of the same scene to produce bifocus images. Depth information can be extracted from the disparities between the image pair. This paper has given the detailed analysis of the system parameters and their appropriate values in long range detection...
