Shafer. Although this is the last topic in this module, shadows contribute a lot to the visual effect of the scene. Through shadows humans distinguish more clearly movement and depth of objects. Shadows are important, but also require more complexity to get right.

Abstract. In this paper, we introduce a framework of human pose estimation from polluted silhouettes due to occlusions or shadows. Since the body pose (and configuration) can be estimated by partial components of the silhouette, a robust statistical method is applied to extract useful information from these by: 1.

Also, vision may be blurred by constantly changing focus, such as looking back and forth between the keyboard and the computer screen.

However, if you are nearing the age of 40, blurry vision may be caused by presbyopia, the loss of the eye's ability to change focus to see near objects (often associated with aging).
