Abstract: A reversible pillow includes first and second panels each having first and second surfaces. The panels each have a plurality of edges. The first and second are panels joined along an edge to define an axis of rotation of the panels relative to one another. A releasable fastener extends along the non-joined edges. The releasable fastener is for fastening the first and second panels to one another. The panels are rotatable about the axis in a first direction such that the first and second panel first surfaces are on an outside of the pillow, and are rotatable about the axis in a second opposite direction such that the first and second panel second surfaces are on the outside of the pillow. The first and second panel first and second surfaces can be fabricated from different materials.

Abstract: Systems and methods for form recognition using visual signatures are disclosed. According to one embodiment, a first form of a first document defined by a first plurality of grids and a second form of a second document defined by a second plurality of grids are received. A determination is made as to whether the first form is similar to the second form by computing a pairwise difference between a first grid of the first plurality of grids with a second grid of the second plurality of grids.

Abstract: Systems and methods for segmentation of report corpus using visual signatures are disclosed. According to one embodiment, a computer-implemented method comprises converting a document to a grayscale image and removing noise from the grayscale image by eroding isolated pixels. Connected regions in the grayscale image are determined and a region of the grayscale image having a square shape is identified. An area of the region is computed and if the area is larger than a threshold, determining that the document contains a form.
