We present an overview of various edge and line oriented approaches to contour detection
that have been proposed in the last two decades. By edge and line oriented we mean …

The basic theory and applications of a set-theoretic approach to image analysis called
mathematical morphology are reviewed. The goals are to show how the concepts of …

The results of a study on multiscale shape description, smoothing and representation are
reported. Multiscale nonlinear smoothing filters are first developed, using morphological …

In the development of digital multimedia, the importance and impact of image processing
and mathematical morphology are well documented in areas ranging from automated vision …

Medical images edge detection is an important work for object recognition of the human
organs and it is an important pre-processing step in medical image segmentation and 3D …

An algorithm is presented for the analysis and quantification of the vascular structures of the
human retina. Information about retinal blood vessel morphology is used in grading the …

Finite depth-of-field poses a problem in light optical imaging systems since the objects
present outside the range of depth-of-field appear blurry in the recorded image. Effective …

Facial feature extraction is an important step in automated visual interpretation and human
face recognition. Among the facial features, the eye plays the most important part in the …

We propose an efficient and deterministic algorithm for computing the one-dimensional
dilation and erosion (max and min) sliding window filters. For a p-element sliding window …

A new color edge detector based on vector differences is proposed. The basic technique
gives as its output the maximum distance between the vectors within a mask. When applied …
