ABSTRACT:
A method of compressing symbolic information stored in a two dimensional matrix of processing elements each containing a binary pixel representing an object mask and an associated multiple-bit valued pixel carrying information related to the object at each of the binary pixels and representative of objects embedded therein. A gated connection network of Processing Elements is formed for each object in the array by comparing the value of the binary pixels stored in each Processing Element with the value of the binary pixels stored in its neighboring Processing elements and closing the gates between Processing Elements that contain the same pixel value and opening the gates between Processing Elements that contain different pixel values. The method sequentially partitions the array matrix into regions and determines, for each gated connection network of Processing Elements in each region, which Processing Elements are at a regional local coordinate minimum and maximum of the array matrix, and assigns a unique source and destination label, respectively, to those Processing Elements. The contents of the multiple-bit valued pixels associated with the binary pixel assigned the source label are combined in a preselected manner with the contents of the multiple-bit valued pixels associated with the binary pixel assigned the destination label. The binary pixel assigned the source label is deleted after combining from any further minimum or maximum coordinate determination.
