Abstract
AbstractA new algorithm for digital representation of a curve is developed using B‐spline functions. This algorithm is applicable to both corner detection and curve representation. When used in conjunction with the previously developed subpixel precision edge detection algorithm, it provides an effective tool for interesting point detection, stereo matching, and motion parameter extraction. Beside corners, portions of a curve with significant change in curvature are detected as significant points (SCP's); B‐spline fitting through these points provides an efficient representation of the curve. The algorithm renders accurate corner detection and curve representation while compressing the data.
