The problem of computing projection, of digitalimages is considered. algorithms are presented that are suitable for implementation in general-purpose imageprocessing and image analysis pipeline architectures. Also, some new pipeline configurations are proposed that achieve a remarkable degree of parallelism in the computation of projection data and, in fact, of many other geometrical descriptors of digitalimages. In particular, random access memories and other dedicated hardware devices are not needed in these algorithms. The effectiveness of the approach and feasibility of the proposed architectures are demonstrated by running the algorithms in commercially available shortpipelines for imageprocessing and analysis. Examples are shown of the use of projection data for machine vision applications.

In this paper we deal with the problem of detecting and segmenting objects in textured dark-field digitalimagery for automated visual-inspection applications. We first present a technique for correcting optical shading effects in conventional dark-field microscopy. After compensating for possible imperfections in the optical setting we address the problem of segmenting objects (defects) in textured dark-field images. The technique that we will follow is based on a sequential application of local operators, which serves the purpose of clustering the object and the background gray levels. This procedure can be considered an extension of average-thresholding-type techniques. Both algorithms for shading correction and object segmentation have fast implementations in general-purpose image-processing pipeline architectures, and therefore they are appealing to real-time computer vision applications. Computational examples showing the appropriateness of the shading-correction procedure as well as the effectiveness of the segmentation wil be discussed.
