An Image Processing Method for Cardiac Motion Analysis

IEEE Transactions on Biomedical Engineering, 1987
A new image processing method is developed to process two-dimensional ultrasound B-scan echo images which makes possible the delineation of the displacement of cardiac boundaries for the precise assessment of infarcted/ischemic regions. An economic image processing system is designed for the purpose.

Motion analysis of long image sequence flow

Pattern Recognition Letters, 1990
Abstract There is much evidence to support the validity of the use of optical flow as a basis for many computational vision tasks. However, optical flow methods are problematic due to inherent errors in the computational methods involved in the processing.

Visual analysis and image motion in locomoting cats

European Journal of Neuroscience, 2001
AbstractDuring locomotion, observers see a characteristic pattern of motion referred to as an optic flow field. To investigate how they make use of this pattern, we have developed a paradigm for testing visual function during locomotion. Foot placement was recorded while cats walked down an alley cluttered with a high density of small objects; the task
