Abstract
An optimal line detector in 1D case is derived from Canny's criteria. The detector is extended to the 2D case by operating in the x direction and in the y direction separately. An efficient implementation using an infinite impulse response (IIR) filter is provided. The performance evaluation of both the proposed detector and the implemented detector is given. The implementation method that we have used is significantly superior to the classical ones in some aspects (e.g. computational time, memory storage). Experimental results show that the use of IIR filter preserves the detector properties.
