ABSTRACT:
A pattern recognition device has a drawing area upon which a user may draw an image with a pen designed for that purpose. In a first option available to the user, a user-drawn image is analyzed and saved in the memory of a computer. In a second option, the image is analyzed and an image in a pre-existing image database of the computer is retrieved which most nearly resembles the drawn image. In both options, the user-drawn image is transformed into a target image which is then subdivided into a plurality of image subdivisions and each image subdivision is then further subdivided into sectors. A first binary value is assigned to each sector to indicate whether or not it has at least some graphical data and a second binary value is assigned to indicate whether or not the graphical data occupies a predetermined percentage of the area of the sector. These binary values are strung together, converted into an integer, and the integers are stored in a computer memory. Since the strung together binary values represent images in compressed numerical form, when the same process is applied to other user-drawn images, the computer can retrieve an image from its memory that most nearly resembles the drawn image by selecting an image in its memory having the nearest numerical value to the drawn image.
