A robust method is presented for features extraction based on structured light images of lap weld joint. On the basis of image processing such as smoothing, adaptive thresholding and thinning, two steps are taken to extract the features of the images. First, the position of the features is located roughly by dividing the centerline into segments and the intercept and slope of each segment obtained...
We propose a method that detects and segments multiple, partially occluded objects in images. A part hierarchy is defined for the object class. Whole-object segmentor and part detectors are learned by boosting shape oriented local image features. During detection, the part detectors are applied to the input image. All the edge pixels in the image that positively contribute to part detection responses...
