摘要： A method of classifying a dent on a surface of a shipping container as being in an acceptable or unacceptable classification includes calculating at least one of an acceptable dent depth range corresponding to the acceptable classification and an unacceptable dent depth range corresponding to the unacceptable classification. The method further includes measuring a depth of the dent with a measurement apparatus and comparing the depth with the acceptable and/or unacceptable dent depth ranges to classify the dent in the acceptable or unacceptable classification. The method of classifying the dent on the surface of the shipping container is accurate and repeatable because it includes measuring the depth of the dent and comparing the depth with the acceptable and unacceptable dent depth ranges. The ability to classify dents allows recipients of the shipping containers to consistently accept or reject shipping containers having dents in the acceptable and unacceptable classifications, respectively.

摘要： A method of producing an enhanced Active Appearance Model (AAM) by combining images of multiple resolutions is described herein. The method generally includes processing a plurality of images each having image landmarks and each image having an original resolution level. The images are down-sampled into multiple scales of reduced resolution levels. The AAM is trained for each image at each reduced resolution level, thereby creating a multi-resolution AAM. An enhancement technique is then used to refine the image landmarks for training the AAM at the original resolution level. The landmarks for training the AAM at each level of reduced resolution is obtained by scaling the landmarks used at the original resolution level by a ratio in accordance with the multiple scales.
