Visuelle Wahrnehmung

8: Many researcher is vision science believe that object recognition is one of the most important functions of the human visual system. Thus it is perhaps not surprising that there exists a large body of research on object recognition.

An opponing theory - usally referred to as view-based models -  instead believes the human visual system recognizes objects by storing and matchin "2D-images" or "snap-shots" of objects and inter- and extrapolates between them if required to recognize an object from a novel viewpoint.

One of the most well-known proponents of this theory is ---. --- both theories are --- connected to the findings, theories and models of early spatial vision.

8: Many researcher is vision science believe that object recognition is one of the most important functions of the human visual system. Thus it is perhaps not surprising that there exists a large body of research on object recognition.

Yamins et al. compared their models both to the response of cells in IT cortex (roughly N = --- cells) as well as on how well the models categorized a set of images (roughly N = --- images). One central finding was that models optimized for --- were also superior at --- .

1: Black-body radiation is ermitted by a black body (an opaque and non-reflective body) held at constant, uniform temperature.

The radiation has aspecific spectrum and intensity that depends only on the temperature of the body. The concept of the black body is an idealization, as perfect black bodies do not exist in nature. Pure graphite, however is a good approximation to a black maerial.
