Abstract: An image input section 1 obtains a halftone image IG of a to-be-measured particle group. A binarization section 2 binarizes the halftone image IT to obtain a binary image IB. A distance transform section 3 performs distance transform for the binary image IB to obtain a distance-transformed image ID. In this case, the particle nucleus extraction section 4 obtains particle nucleus candidates from the distance-transformed image ID and extracts a particle nucleus on the basis of the distance between the particle nucleus candidates and a separation parameter PS to obtain a particle nucleus image IC. A particle expansion section 5 performs particle expansion processing for the particle nucleus image IC and distance-transformed image ID to obtain a particle-separated image IS. In this case, the particle expansion section 5 performs particle expansion processing for the particle nucleus in the particle nucleus image IC along the value of distance transform to obtain the particle-separated image IS.

Abstract: According to a data conversion method and apparatus, an original signal is wavelet-transformed with a desired expansion count to generate transformed data. The transformed data is corrected such that a difference between the original signal and a value obtained by inversely wavelet-transforming the transformed data falls within a desired tolerance range, thereby generating the corrected transformed data as compressed data in which the original signal is compressed.
