Claim Text:
1. A process of determining features of a fabric, the process comprising: forming a representation of a portion of a surface of the fabric, the representation showing locations and sizes of knuckles and pockets in the surface of the fabric; generating an image of the portion of the surface of the fabric based on the representation; displaying at least a portion of the image on a screen associated with a computer having a processor; drawing an outline around at least one of the knuckles in the displayed image; drawing guidelines in the displayed image such that the guidelines (i) pass through the center of the outlined knuckle, (ii) pass through the other knuckles, and (iii) form shapes that surround areas of the image that correspond to where the pockets are formed between the knuckles, the shapes being non-rectangular parallelograms, wherein the outline and the guidelines are drawn using an image analysis program stored in a non-transitory computer-readable medium; a step of determining at least one of (i) a length of the outlined knuckle, (ii) a width of the outlined knuckle, (iii) orientation angles of the guidelines, and (iv) locations of the knuckles along the guidelines, wherein the determining step is performed by the image analysis program; and calculating at least one of (i) a percentage of the surface of the fabric that corresponds to the knuckles and (ii) a density of the pockets, wherein the calculating step uses the determinations of the length of the outlined knuckle, the width of the outlined knuckle, the orientation angle of the guidelines, locations of the knuckles along the guidelines, and a calculated area of at least one of the parallelograms.
