A solid-state device for presenting moving shadows

A solid state device for measuring sensitivity to thermal pain.

WALKER, J. M. AND W. C. DIXON. A solid state device for measuring sensitivity to thermal pain. PHYSIOL BEHAV 30(3) 481-483, 1983.--A simple and inexpensive circuit for use in conducting the tail-flick test is described. The use of digital integrated circuits coupled to a thyristor phase control circuit holds the number of parts needed to minimum. Methods for the use of the device and statistica...

Learning Moving Cast Shadows for Foreground Detection

We present a new algorithm for detecting foreground and moving shadows in surveillance videos. For each pixel, we use the Gaussian Mixture Model (GMM) to learn the behavior of cast shadows on background surfaces. The pixelbased model has the advantages over regional or global model for their adaptability to local lighting conditions, particularly for scenes under complex illumination conditions...

2d Shape Estimation for Moving Objects Considering a Moving Camera and Cast Shadows

The estimation of the 2D shape of moving objects in a video image sequence is required for many applications, e.g. for so-called content-based functionalities of ISO/MPEG-4, for object-based coding, and for automatic surveillance. Many real sequences are taken by a moving camera and show moving objects as well as their cast shadows. In this paper, an algorithm for 2D shape estimation for moving...

Detecting Moving Shadows: Formulation, Algorithms and Evaluation

Moving shadows need careful consideration in the development of robust dynamic scene analysis systems. Moving shadow detection is critical for accurate object detection in video streams, since shadow points are often misclassified as object points causing errors in segmentation and tracking. Many algorithms have been proposed in the literature that deal with shadows. However, a comparative eval...
