Hardware Design Considerations for Edge-Accelerated Stereo Correspondence Algorithms

Table 5

Frame rate versus image size for Systems 1–4 (disparity range = 64, support window size = 11 × 11).

Image size	𝑤/𝑜 edge detector*		𝑤/edge detector
	Fixed-support	ADSW	Fixed-support	ADSW
320 × 240	1225	34	2570	174
640 × 480	315	8	645	45
800 × 600	203	5	412	30
1024 × 768	124	3	252	18
1280 × 1024	75	1	150	7

^∗The frame rates for the systems without the edge detectors are projected frame rates.
