Abstract: A first method for exact and inexact matching of documents stored in a document database includes the step of converting the documents in the database to a compacted tokenized form. A search string or search document is then converted to the compact tokenized form and compared to determine if the test string occurs in the documents of the database or whether the documents in the database correspond to the test document. A second method for inexact matching of a test document to the documents in the database includes generating sets of one or more floating point values for each document in the database and for the test document. The sets of floating point numbers for the database are then compared to the set for the test document to determine a degree of matching. A threshold value is established and each document in the database which generates a matching value closer to the test document that the threshold is considered to be an inexact match of the test document.

Abstract: An apparatus and method for editing an entire image, including closed areas surrounded by other closed areas, contained within a framed area is disclosed. Image data obtained through a prescan is first written into a bit map memory, in the form of first data, e.g., 5. A closed area containing a point designated by a user is then painted with data of 3, for example. The entire area outside the closed area is painted with third data of 1, for example, using a start point that is a point outside the area of the original. Further, the bit map memory is painted with fourth data, e.g., a function number N corresponding to the type of the preset image edit processing, with the designated point as a start point of the painting and the third data as a pattern delineating the area painted with the fourth data. Through the above steps of processing, the framed area is entirely painted with the number N. Then, the number N is set to the value corresponding to the type of image edit processing.
