Abstract: Embodiments of the present disclosure pertain to computer-implemented methods of reconstructing a fiber length distribution of a fiber from its fibrogram by receiving the fibrogram; determining an end of the fibrogram; applying a windowed curve-fitting procedure to smoothen the fibrogram curvel and estimating the fiber length distribution of the fiber from the smoothened fibrogram curve. The methods may also include one or more steps of reconstructing an initial and missing portion of the fibrogram; assessing fiber quality based on the estimated fiber length distribution; adjusting one or more fiber-related conditions based on the estimated fiber length distribution; and repeating the method after the adjustment. Additional embodiments pertain to computing devices for reconstructing a fiber length distribution of a fiber from its fibrogram.

Abstract: Disclosed is a system and method for extraction of information of within sample distribution of fiber quality from high-volume instrument (HVI) fibrogram to better predict yarn quality than the standard HVI output. The present invention allows for information on fiber quality to be obtained while avoiding testing samples with more expensive techniques. The disclosed system and method extracts HVI data for collecting a respective set of initial fibrograms from a set of fiber samples and representing them as a distance matrix to form a matrix of transformed fibrogram data, said matrix of transformed fibrogram data comprising a vector of scores to represent each sample and thereafter explaining variation in yarn quality by extracting all of the information available from the fibrogram.

Abstract: Fabric wrinkles are automatically evaluated using a reliable, accurate, affordable, and efficient system. Two algorithms are used, the facet model algorithm and the plane-cutting algorithm, to extract features for evaluating wrinkles in fabrics. These algorithms eliminate the need for independent evaluation of a fabric specimen by a technician.
