WebApr 6, 2016 · ABSTRACT Project Abstract This project proposes the development and demonstration of a label-free sensing instrument based on the integration of an electronically controlled linear swept-frequency semiconductor laser, a high quality factor (Q) optical resonator with covalent surface functionalization, and a microfluidic cell for … WebThe Dense Optical Flow algorithm estimates the motion vectors in every 4x4 pixel block between the previous and current frames. Its uses include motion detection and object tracking. The output below represents each vector in the HSV color space, where the hue is related to the motion direction, and the value is proportional to the speed.

WebOptical flow is the pattern of apparent motion of image objects between two consecutive frames, caused by the movement of object or camera. It is a 2D vector field, where each vector is a displacement vector showing the movement of points from first frame to second.

WebOct 27, 2011 · You want to compute the individual partial derivatives of the optical flow field; one for the x direction, and one for the y. Split your flow array/matrix into two matrices: x and y flow. For each of those, you could go the naive route and just do a simple difference: derivative = current_state - last_state.
