The binary Hough transform-theory, real time implementation and application to visual inspection

The binary Hough transform (BHT) as well as its implementation and applications to visual inspection have been briefly presented and discussed. It has been verified that it provides some interesting features and could be an effective option for application in visual inspection and to produce the representation of the digital images by endpoints of its straight line segments to be used for posterior higher level recognition. Its fast execution in software and hardware makes it an interesting option for real time applications. Further developments being addressed by the authors include: theoretical analysis of the BHT accuracy and effectiveness, bit-level versions of the BHT systolic architectures, a hierarchical BHT, a BHT based on trivial line segments, application of the BHT to image compression and the usage of the BHT systolic architectures for other DSP and image processing tasks (e.g. filters, convolvers)
