In photography, an infinity cove or infinity cyclorama is an all-white space with no corners, designed to give the impression that the background of an object extends to infinity. Infinity coves range from a simple roll of paper to whole studios (often used for photographing cars). The principle of design is that everything behind the object is ...
The pixels with the largest gradient values in the direction of the gradient become edge pixels, and edges may be traced in the direction perpendicular to the gradient direction. One example of an edge detection algorithm that uses gradients is the Canny edge detector. Image gradients can also be used for robust feature and texture matching.
Schlieren photography is a process for photographing fluid flow. Invented by the German physicist August Toepler in 1864 to study supersonic motion, it is widely used in aeronautical engineering to photograph the flow of air around objects.

H mag (R) denotes the normalized histogram of gradient magnitudes of region R, and H dir (R) denotes the normalized histogram of gradient orientations of region R. Both are normalized according to the size N R Then F m a g , d i r = ( H m a g ( R ) , H d i r ( R ) ) {\displaystyle F_{mag,dir}=(H_{mag}(R),H_{dir}(R))} is a quantitative texture ...
The top layer (the bird) is partially transparent, so the background clearly can be seen through its wing. In this picture the top layer has a drop shadow , a red color overlay of 40%, a gradient overlay from red to yellow of 20% opacity, and a slight bevel effect.
