Abstract Due to the influence of objective environmental conditions in image acquisition stage, quality existing methods is poor, which makes effect defect detection not ideal. In this paper, research on product appearance based deep learning machine vision proposed. A model constructed by using a Gaussian mixture, and multiple sub-images with different sizes are used as data support multi-scal...

We propose a method for the matching of characteristics of stereo images based on the concepts of an initial global match and the foveation of the images. We present several macular tilings that can be used in the foveation process. Given a pair of cameras that image a static scene, vergence is achieved at a minimun of the mse difference between the two corresponding macular images.

Vision begins at the retina, a light-sensitive tissue at the back of the eye that comprises highly organized, laminated networks of nerve cells. Investigating the mechanisms of retinal development is fundamentally important to gaining a basic knowledge of how vision is established. In this book, we present the sequence of developmental events and the mechanisms involved in shaping the structure...

The prevailing view of Nagaoka's "Saturnian" atom is so misleading that today many people have an erroneous picture of Nagaoka's vision. They believe it to be a system involving a 'giant core' with electrons circulating just outside. Actually, though, in view of the Coulomb potential related to the atomic nucleus, Nagaoka's model is exactly the same as Rutherford's. This is true of the Bohr ato...

Zoos and aquaria are dynamic informal learning environments that require constant sensory (often visual) access, and are thus often inaccessible to visitors with vision impairments. There remain few guidelines for designing accessible dynamic exhibits. We present a model of mediated visitor-exhibit interaction that begins to address this class of environments. We discuss plans to operationalize...

Readers tend to skip words, particularly when they are short, frequent, or predictable. Angele and Rayner (2013) recently reported that readers are often unable to detect syntactic anomalies in parafoveal vision. In the present study, we manipulated target word predictability to assess whether contextual constraint modulates the-skipping behavior. The results provide further evidence that reade...
