Particle-Group Movement Analysis System, Particle-Group Movement Analysis Method and Program

A particle-group movement analysis system comprising:

• an image capture means which captures a time-series image of a plurality of objects in a form of a particle;
• a characteristic information computing means which calculates characteristic information related to the object in the form of a particle inside each small area corresponding to each pixel in the time-series image which is captured;
• a time-change detecting means which detects a time change of the characteristic information;
• and
• a factor specifying means which specifies an abnormal area which is an area including the object in the form of a particle which has become a cause of the time change, or an abnormal area which is an area near the object in the form of a particle which has become a cause of the time change.

A particle-group movement analysis method comprising:

• an image capture step of capturing an image of a plurality of objects in a form of a particle;
• a characteristic information computing step of computing characteristic information related to an object in the form of a particle in each small area corresponding to each image pixel in the time-series image which is captured;
• a time-change detection step of detecting a time change of the characteristic information;
• and
• a factor specification step of specifying an abnormal area which is an area including the object in the form of a particle which has become a cause of the time change, or an abnormal area which is an area near the object in the form of a particle which has become a cause of the time change.

A program for a particle-group movement analysis system which analyzes a movement of an object in a form of a particle, which is readable by a computer, and causes the computer to function as:

• an image capture means which captures a time-series image of a plurality of objects in a form of a particle;
• a characteristic information computing means which calculates characteristic information related to the object in the form of a particle inside each small area corresponding to each pixel in the time-series image which is captured;
• a time-change detecting means which detects a time-change of the characteristic information;
• and
• a factor specifying means which specifies an abnormal area which is an area including the object in the form of a particle which has become a cause of the time change, or an abnormal area which is an area near the object in the form of a particle.
