TLDR
A new transform is presented that utilizes local radial symmetry to highlight points of interest within a scene and is seen to offer equal or superior performance to contemporary techniques at a relatively low-computational cost.Abstract:
A new transform is presented that utilizes local radial symmetry to highlight points of interest within a scene. Its low-computational complexity and fast runtimes makes this method well-suited for real-time vision applications. The performance of the transform is demonstrated on a wide variety of images and compared with leading techniques from the literature. Both as a facial feature detector and as a generic region of interest detector the new transform is seen to offer equal or superior performance to contemporary techniques at a relatively low-computational cost. A real-time implementation of the transform is presented running at over 60 frames per second on a standard Pentium III PC.read more

Multiple-instance learning for breast cancer detection in mammograms
Ruben Sanchez de la Rosa,Mathieu Lamard,Guy Cazuguel,Gouenou Coatrieux,Michel Cozic,Gwenole Quellec +5 more
TL;DR: An experimental computer-aided detection and diagnosis system for breast cancer, the most common form of cancer among women, using mammography using the Multiple-Instance Learning (MIL) paradigm, which has proven useful for medical decision support in previous works from the team.

Quality assessment of Ki67 staining using cell line proliferation index and stain intensity features
Mathias Buus Lanng,Cecilie Brochdorff Møller,Anne-Sofie Hendrup Andersen,Ásgerður Arna Pálsdóttir,Rasmus Røge,Lasse Riis Østergaard,Alex Skovsbo Jørgensen +6 more
TL;DR: A Ki67 stain quality model based on ordinal logistic regression was developed to determine the quality of a staining protocol from features extracted from the segmented celluclei in the cell lines, and shows great promise for using cell nuclei information from cell lines to predict the staining quality of staining protocols.

Watermarking based on unified pattern recognition framework
Mandyam D. Srinath,Bing Ouyang +1 more
TL;DR: A new blind image watermarking scheme using a novel pattern recognition framework is presented and demonstrates that this proposed framework overcomes the limitation of existing moments-based approaches in dealing with geometric attacks that involve image cropping/padding operations.

An automated process for deceit detection
TL;DR: In this paper, the role of dynamic eye-based features such as eye closure/blinking and lateral movements of the iris in detecting deceit was investigated and the features were recorded both when the test subjects were having nonthreatening conversations and when they were being interrogated about a crime they might have committed.

Use of the Hough transformation to detect lines and curves in pictures

TL;DR: It is pointed out that the use of angle-radius rather than slope-intercept parameters simplifies the computation further, and how the method can be used for more general curve fitting.

Algorithms for defining visual regions-of-interest: comparison with eye fixations
C.M. Privitera,L.W. Stark +1 more
TL;DR: This paper investigates and develops a methodology that serves to automatically identify a subset of aROIs (algorithmically detected ROIs) using different image processing algorithms (IPAs), and appropriate clustering procedures, and compares hROIs with hROI as a criterion for evaluating and selecting bottom-up, context-free algorithms.

Context-free attentional operators: the generalized symmetry transform
TL;DR: An attention operator based on the intuitive notion of symmetry, which generalized many of the existing methods of detecting regions of interest is presented, a low-level operator that can be applied successfully without a priori knowledge of the world.
