Methods of inspecting cellular articles such as cellular ceramic articles are disclosed, wherein the methods comprise characterizing a web structure from intensity values of a digital image. One method comprising establishing an edge location for each of the walls of the web, and an edge intensity slope SE for each edge location, and then searching for a wall intensity slope SW in one of the web walls of the characterized web structure to determine the location of a web defect. Another method involves determining at least one characteristic that defines a conforming cell, then identifying a non-conforming cell region based on the at least one characteristic, and then examining the walls within the non-conforming cell region to locate the defect in one of the walls within the non-conforming cell region.
A method of inspecting a web of a cellular article, wherein the web is defined by walls each having a width and a length and that in turn define an array of cells, the method comprising:
A method of locating a defect in a web of an extruded cellular ceramic article, wherein the web is defined by walls each having a width and a length and that in turn define an array of cells comprising:
