Title: Curvilinear surface tension measurement method
Inventor: SAKAMOTO HIROYASU
IPC: G01N13/02
Filed: 2002-09-27
Abstract: <P>PROBLEM TO BE SOLVED: To raise accuracy and speed of a curvilinear surface tension measurement method using image processing.  <P>SOLUTION: The curvilinear surface tension measurement method measures a surface tension by applying a curve of a liquid-drop shape generated by theoretical calculations to an image formed by imaging a suspended liquid drop or a still liquid drop, in such a manner as to include the minimum error. In this method, a contour position determination method, in which a maximum likelihood estimation method known in statistics is used. For effectively and highly accurately obtaining a curve application error between the liquid drop shape of the observed image and a theoretical curvilinear shape, the curve application error is measured, with respect to a curve of a polynomial interpolating a dot sequence of the liquid drop shape with the minimum error, from points on the curve of the theoretical curvilinear shape. If there is still a time before a next scheduled measurement is started, a global optimum solution is repeatedly searched for within the allowable time so as not to cause the applied curve to include a local minimum error.  <P>COPYRIGHT: (C)2004,JPO
