Abstract

Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes’ horizontal separation. Bio-inspired systems aim to extract some interesting features from living beings, such as adaptability and fault tolerance, for including them in human-designed devices. The biological vision systems routinely accomplish complex visual tasks such as object recognition, stereoscopic vision and many more, which continue to challenge artificial systems. If any cell in the brain is dead, other cell takes over the dead cell and brain works in the normal way. Any bio-inspired system must be any day superior to any artificial method. In this paper, this paper presents some algorithms which are motivated from biological functioning, such as Cepstral filtering technique, phase method, reaction-diffusion algorithm. Further, this pa per compares cepstral filtering technique with phase method. These two algorithms are claimed as two different approaches, but in this paper we show that in essence they are same. Both the algorithms exploit only part of the functions used in the bio logical flow of data to reconstruct the depth perception. The algorithms look different as both follow different procedures and functions. If the computational steps are decomposed and compared then they are doing the same thing. Each step in both algorithms is same and only the functions used are different as they are just the mathematical way of representation. By comparing both the algorithms, the advantage of one can be benefited by the other. The equivalence condition has also been derived.
