Title: Grain discriminator
Inventor: YAMAMOTO SOICHI
IPC: G01N33/02
Filed: 2002-10-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a grain discriminator for discriminating grains by a simple calculation.  <P>SOLUTION: The grain discriminator generates a grain image 18 of a grain 14 by photographing with a photographing device. The discriminator divides the grain image into four regions with a longest main inertia axis S of the grain 14 and a central vertical axis T that crosses and is orthogonal to the center of the axis S, counts the number of pixels in each region, and calculates a maximum pixel number difference by subtracting a smallest pixel number from a largest pixel number in each region. When the maximum pixel number difference is less than a predetermined threshold value, the grain 14 is determined to have a normal grain size. When the maximum pixel number difference is larger the predetermined threshold value, the grain 14 is determined to have an abnormal size. Whether the grain 14 has a normal size can be determined by the simple calculation, specifically by counting the pixel number in each region of the grain image 18 and calculating the maximum image number difference.  <P>COPYRIGHT: (C)2004,JPO
