Image Enhancement in Sports Recordings
A video signal representing rapid ball movement is produced from a series of source images. An initial image position for the moving ball is identified by, for each image, producing a difference image between sequential images. In the difference image, image elements representing a contents alteration below a threshold are allocated a first value, and those representing a contents alteration above or equal to the threshold are allocated a second value. A set of candidates is then identified, where each candidate is represented by a group of neighboring image elements that all contain the second value. The group must fulfill a ball size criterion. A ball selection algorithm selects an initial image position from the set of ball candidates. The ball is tracked, and a composite image sequence is generated wherein a synthetic trace representing the path of the moving ball is shown as successively added image data.

Convertible plush toy with storage
A convertible plush toy can convert between two interconnected reversible shapes. The first shape is that of a plush buddy, such as a teddy bear, that may be reversed into a second, ball shape. The construction and relationship of the ball form to the teddy bear abdomen creates a hidden hollow storage compartment within the plush buddy. The ball size, the abdomen measurements and construction, and the shared opening are designed in such a way to allow the internalized form to support the externalized form, while providing enough independence to avoid distortion of the externalized shape. The ball configuration can be designed in a semi-rigid form, such as with an external plush, internal batting and inner lining, so that the ball retains its shape when externalized and also provides definition to the storage space when internalized.
