초록 ▼

Digital image data compression apparatus includes a controller circuit for receiving digital image data and for processing the image data into blocks. The controller circuit supplies processed image data to a plurality of transform circuits and to a feeder circuit. The transform circuits receive data from the controller circuit and the feeder circuit, and provide parallel processing to compare blocks of image data and generate fractal transform values representing the image data in a compressed form.

대표청구항 ▼

Apparatus for generating signals representing an image in compressed digital form, comprising: a memory for storing digital signals comprising digital image data representative of the image and for storing transformed data; a control circuit coupled to the memory for receiving the digital image data, for subdividing the digital image data into a set of domain blocks and a set of range blocks each comprising pixel brightness data, for creating sets of multiple orientation blocks for the domain blocks each comprising pixel brightness data, for determining average brightness values for the domain and range blocks, for receiving transformed data corresponding to the domain blocks, for accumulating the transformed data in the memory, and for supplying the accumulated transformed data as output signals comprising a compressed digital representation of the image; a data feeder circuit coupled to the control circuit for receiving the range block pixel brightness data and the range block average brightness values, and for creating intermediate range block values from the range block pixel brightness data and the range block average brightness values; and a plurality of fractal transform circuits coupled to the control circuit and the data feeder circuit, for individually receiving at least one set of orientation blocks and the intermediate range block values, for simultaneously determining for each domain block corresponding to the received set of orientation blocks a block pair including a selected orientation block and a selected range block which have the greatest similarity of all possible block pairs, for simultaneously generating transformed data for each domain block, the transformed data representing the selected orientation block and range block for each domain block, and for supplying the transformed data to the control circuit.
