BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device for the moments of image data, and more particularly to a device for calculating the moments of image data at high speed through a simple arrangement.
2. Description of the Related Art
It is widely known to process image data by determining its moments in order to detect information represented by the image data. The moments of image data used include a zero-order moment, a primary moment, a secondary moment, and the like.
The zero-order moment is used to recognize the brightness of an image, the primary moment the position of a one-dimensional object, and the secondary moment the two-dimensional positional information of an object. In order to determine these image data moments, as many calculations as the number of pixels have to be carried out. Hence a vast amount of data must be processed, thus requiring a high-speed processing device. Since it would be impractical in terms of time consumption to process such image data with an ordinary computer through implementation of software, an image processing engine is used as special image processing hardware for processing the image data.
The image processing engine which has heretofore been used is however problematic in that it has a considerably complex structure because it processes image data in versatile applications.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a device for calculating the moments of image data at high speed through a simple arrangement.
In order to eliminate the aforesaid problems, there is provided in accordance with the present invention a device for calculating the moments of image data, comprising: an image frame memory for storing original image data; an image frame memory for storing processed data; an image frame memory for storing weight data in a horizontal direction; an image frame memory for storing weight data in a vertical direction; a constant generator for calculating weight data; an adder coupled to the image frame memories through a bus; a multiplier coupled to the image frame memories through a bus for multiplying the data between the image frame memories; an accumulator coupled to the adder and the multiplier through another bus for temporarily storing calculated results; and calculating means for calculating zero-order, primary, and secondary moments of the image data.
The zero-order moment is determined by adding the original image data stored in the image frame memory successively into the accumulator by using the adder.
The primary moment is determined by storing a 1 in the upper lefthand end of the image frame memory, generating data which are successively 2, 3, 4 and so on by adding a 1 to the previous data value so that subsequent neighboring locations to the righthand side produce the weight data, storing these weight data in the image frame memory which serves to store weight data in the horizontal direction, determining the products of the original image data stored in the image frame memory and the weight data with the multiplier, and finally adding the products with the accumulator.
The secondary moment is determined by generating horizontal weight data in the image frame memory which serves to store weight data in the horizontal direction, generating vertical weight data in the memory which serves to store weight data in the vertical direction, determining the products of pixels in these two image frame memories with the multiplier, storing the products in the image frame memory which serves to store weight data in the horizontal direction, determining the products of these weight data and original image data for the respective pixels with the multiplier, and finally adding the products with the accumulator.
