The reduction of transmitted light at 650 nm caused by scattering from fibrin polymers as they develop in a clotting plasma sample has proven effective for following the course of the coagulation. An instrument designed on this principle and using entirely solid-state electronics has yielded clotting time reproducible to within ±15%, and has enabled ...

Analysis of photometric factors based on photometric linearization
Journal of the Optical Society of America A, 2007We propose a method for analyzing photometric factors, such as diffuse reflection, specular reflection, attached shadow, and cast shadow. For analyzing real images, we utilize the photometric linearization method, which was originally proposed for image synthesis.

Conventional photometric stereo recovers one normal direction per pixel of the input image. This fundamentally limits the scale of recovered geometry to the resolution of the input image, and cannot model surfaces with subpixel geometric structures. In this paper, we propose a method to recover subpixel surface geometry by studying the relationship ...

The author compares the photometric effects of motion (which is defined as the variation of a point's imaged intensity as a consequence of motion) and the geometric effects of motion (which is defined as the variation in projected surface geometry as a consequence of motion).

Classification of Photometric Factors Based on Photometric Linearization
2006We propose a new method for classification of photometric factors, such as diffuse reflection, specular reflection, attached shadow, and cast shadow. For analyzing real images, we utilize the photometric linearization method which was originally proposed for image synthesis. First, we show that each pixel can be photometrically classified by the simple
