摘要： A holding apparatus includes an anchor plate including upper and lower sections and a core member sandwiched medially of the upper and lower sections. A bore passes through the upper and lower sections and the core member. A plurality of elongated support legs are connected to the anchor plate and are adaptable along opposing radial paths. An elongated support rod is included for axially receiving and supporting the filter. The support rod is engageable with the anchor plate such that the support rod becomes aligned along a vertical plane while extending away from the anchor plate. The apparatus further includes a locking wedge having an inverted conical shape and an elongated sleeve formed therein for attaching to the support rod. The locking wedge engages the filter such that the filter becomes positioned between the locking wedge and the anchor plate. The locking wedge includes threadably adjustable spherical gripping members.

摘要： Apparatus and methods for producing segmentations of images which contain text. The general approach is to locate a first set of components which contain text characters, locate a second set of components which do not contain text characters, sort the second set using a characteristic shape, make a cover set from the sorted second set, and use the cover set to locate the portions of the image which contain text. An embodiment is disclosed in which the method is applied to texts employing the Manhattan layout to locate columns of text. In the embodiment, parts of the image which do not contain text are located by constructing maximum empty rectangles which do not contain characters. Based on the observation that columns in Manhattan layouts are separated by rectangles with a high aspect ratio, the maximum empty rectangles are sorted in a manner which favors such rectangles to produce the cover set. Also disclosed are methods for locating maximum empty rectangles defined by points and for locating maximum empty rectangles defined by rectangles containing characters.
