An image gradient is a directional change in theintensity or color in an image. The gradient of theimage is one of the fundamental building blocks in imageprocessing. For example, the Canny edge detector uses imagegradient for edge detection.
People also ask, what is the mean of Gradient?
noun. the degree of inclination, or the rate of ascentor descent, in a highway, railroad, etc. an inclined surface;grade; ramp. Physics. the rate of change with respect to distanceof a variable quantity, as temperature or pressure, in thedirection of maximum change.
Similarly one may ask, what is gradient magnitude?
The magnitude of the gradient is themaximum rate of change at the point. The directional derivative isthe rate of change in a certain direction.
Orientation of edge pixels implies theirdirection. For instance, an edge may have a verticalorientation (pixels on a vertical line/curve) or ahorizontal orientation (pixels on a horizontal line), or itmay be slanted. You can represent the edge orientation by anangle (in degrees or radians).
