IMAGE ANALYZER

摘要

PURPOSE:To attain quantitative representation of an inclusion and a deposit by their existing position by providing a line element extracting section in a matrix texture and a texture information extracting section in parallel in addition to an inclusion/deposit extracting section so as to store the result of extraction of them. CONSTITUTION:An object is read by an image pickup device 2 as optical picture information, fed to an A/D converter 3 and converted into 1-byte (256 gray tones) digital information. The converted information is fed to extraction sections 4-6 and the characteristic of a metallographic structure is decomposed and obtained as three elements of inclusion, deposit and texture. The characteristic decomposed into the three elements is stored in storage devices 7-9 of 512X512 elements. The storage device 7 is preset with a rate of a prescribed black part and the information not reaching it is rejected. The information having an area is rejected and only the line element is stored in the device 8. The result of extraction of texture information is stored in the device 9. Deposited carbide existing in grain boundary and the carbide in the grain are subject to quantitative processing with decomposed by applying processing at a quantitative processing section 10.
