A Fourier theory for cast shadows
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2004Cast shadows can be significant in many computer vision applications, such as lighting-insensitive recognition and surface reconstruction. Nevertheless, most algorithms neglect them, primarily because they involve nonlocal interactions in nonconvex regions, making formal analysis difficult.

Early Years Educator, 2021
The pandemic has hit disadvantaged families particularly hard and the rise of domestic abuse in lockdown has been described by the UN as a ‘shadow pandemic’. Sue Cowley analyses the wider implications for children's education and well-being, and what practitioners need to consider.

ACM SIGGRAPH ASIA 2009 Courses, 2009
Shadows are crucial for enhancing realism and provide important visual cues. In recent years, many important contributions have been made both for hard shadows and soft shadows. Often spurred by the tremendous increase of computational power and capabilities of graphics hardware, much progress has been made concerning visual quality and speed, making ...

Algorithms for antialiased cast shadows
Computers & Graphics, 1985Abstract The ability to render the shadows cast by objects in a scene is of prime importance in augmenting the realism of sequences produced by image synthesis algorithms. From a theoretical standpoint, the problem does not present a great number of difficulties: It requires an integration in the process, of the viewpoint from the light source and ...

Cast Shadows in Wide Perspective
Perception, 2011We investigated the apparent spatial layout of cast shadows up to very wide fields of view. We presented up to 130° wide images in which two ‘flat poles’ were standing on a green lawn under a cloudless blue sky on a sunny day. The poles threw sharp cast shadows on the green, of which one was fixed.
