ABSTRACT:
The first aspect of this invention relates to a peak data extracting device used in picture processing devices. The peak data extracting device comprises a DDA (data differential analysis) computing unit, an peak filter and a sorting unit. The computing unit gives Hough curves (sine curves) based on points to be processed on an original picture. The peak filter extracts peak data. The sorting unit sorts the peak data extracted with the noise components removed.
The second aspect of this invention relates to a rotary motion recurrence formula computing device which are used in the DDA computing unit. The device computes the rotary motion formula
