The performance in judging values in a univariate map encoded using five different color scales was tested in eleven subjects. Digital elevation maps (DEMs) were encoded using: 1) an RGB gray scale (RGB), 2) a gray scale based on CIELAB L* (L*), 3) a L* scale with an added red hue component (Red L*), 4) an L* scale with continuous hue change (Spectral L*), and 5) a gray scale based on luminance...

In this work, gray-scale invariant ranklet texture features are proposed for false positive reduction (FPR) in computer-aided detection (CAD) of breast masses. Two main considerations are at the basis of this proposal. First, false positive (FP) marks surviving our previous CAD system seem to be characterized by specific texture properties that can be used to discriminate them from masses. Seco...

objective(s): as heat, pain is one of the most common clinical symptoms. generally, calcitonin (ct) is prescribed as an analgesic agent for the treatment of pain, especially for the pain caused by osteoporosis or primary and metastatic bone tumor. however, the detailed mechanism remains unknown.materials and methods: in this study, chronic constriction injury (cci) rat model was created, and ho...

This paper describes the implementation of a multi-channel autofocusing scheme capable of automatically extracting gray-level shape scales. The scale concept in the vision literature stands for the characteristic length over which gray-level variations in the image take place and/or the operator size used for processing the given image. The proposed scheme allows for a data-driven multichannel ...
