A new edge detection algorithm and its applications in picture processing
TLDR
In this paper, a new edge detector which is better than the gradient-type edge detectors used so far is presented, where the edge detector is appended to an image, a picture is obtained consisting of edge points.About:

A survey on image segmentation
King-Sun Fu,J. K. Mui +1 more
TL;DR: This survey summarizes some of the proposed segmentation techniques in the area of biomedical image segmentation, which fall into the categories of characteristic feature thresholding or clustering and edge detection.

The detection of intensity changes by computer and biological vision systems
TL;DR: The implementation of a theory for the detection of intensity changes, proposed by Marr and Hildreth, where the image is first processed independently through a set of different size operators, whose shape is the Laplacian of a Gaussian, ▿2G(x, y).

Automatic detection of rib borders in chest radiographs
TL;DR: An algorithm for detection of posterior rib borders in chest radiographs is presented and the algorithm first determines the thoracic cage boundary to restrict the area of search for the ribs, then finds approximate rib borders using a knowledge-based Hough transform and localizes the ribs using an active contour model.

Application of digital image analysis in dental radiography for the description of periapical bone lesions: a preliminary study
André Mol,P.F. van der Stelt +1 more
TL;DR: The use of digital image analysis in dental radiography for the description of periapical bone lesions is described to circumvents the problem of observer variability and can eventually be used for the quantitative assessment of bone lesions.

On the Quantitative Evaluation of Edge Detection Schemes and their Comparison with Human Performance
J.R. Fram,E.S. Deutsch +1 more
TL;DR: A technique for the quantitative evaluation of edge detection schemes is used to assess the performance of three such schemes using a specially-generated set of images containing noise to relate the quantitative comparison to real-life imagery.

Pattern recognition of chest X-ray images
TL;DR: The method for recognition of rib images is described in detail, and the procedure employed here is very unique as a processing method for complex pictures and constitutes the most important part of the system for deriving final decisions correctly.
