| Research Abstract |
Fast focus mechanism with constant magnification and a method of visually tracking an object were developed to build a bio-mimetic machine vision system. A tiny varifocal lens was devised to realize a fast focus mechanism. It worked perfectly under both parallel and perspective projections and was used to generate images of a moving object entirely in focus at a rate of 30 Hz. A robust method for visually tracking an object moving in a water of low visibility against complicated backgrounds was developed by combining gray value equalization, coarse region extraction by binarization, template matching based on scale-invariant feature transform(SIFT), and voting for object translations and rotations by the matching results.
