The discrete auto-covariance function could include points associated with positive numbers of whole pixels, and the first positive local maximum of the discrete auto-covariance function could be identified at one of the points. Sub-pixel estimation could also be performed using the point associated with the first positive local maximum and one or more neighboring points. Performing the sub-pixel estimation could include fitting a polynomial curve to the point associated with the first positive local maximum and the one or more neighboring points and identifying a number of whole and fractional pixels associated with a maximum of the polynomial curve. | 04-23-2015 |

The analysis unit includes one or more computer processors configured to examine changes in the wireframe model data to identify a historical trend of changes in the image data. The analysis unit is configured to compare the historical trend of the changes in the image data with designated patterns of changes in the wireframe model data to determine when to request at least one of repair, inspection, or maintenance of the route. | 10-15-2015 |
20150294443 | COMPUTATIONALLY EFFICIENT METHOD FOR IMAGE SEGMENTATION WITH INTENSITY AND TEXTURE DISCRIMINATION - An automatic method for depicting texture in a digital image is provided. A category is automatically assigned to each pixel in the digital image based on one of a set of brightness values associated with the pixel. Each of the brightness values corresponds to a range of intensities associated with the pixels in the digital image, and one of a set of texture values associated with the pixel. Each of the texture values corresponds to a range of differences in the value between the intensity of the pixel and the intensity of neighbors of the pixel. A shading level is automatically assigned to each of the pixels based on the categories. A processed image is automatically produced based on the shading levels, the processed image indicating the texture in the image. | 10-15-2015 |

20160048730 | IDENTIFICATION METHOD, IDENTIFICATION SYSTEM, MATCHING DEVICE, AND PROGRAM - The present invention addresses the problem of acquiring information regarding a component or product and identifying said component or product easily and inexpensively. The present invention has an image-feature storage, an extracting means, an acquiring means, and an identifying means. The image-feature storage stores image features of texture patterns formed on components or products. The extracting means extracts an n-dimensional-symbol image and a texture-pattern image from a taken image containing at least the following: an n-dimensional symbol (n being a natural number) that represents information regarding a component, a product, or a product comprising said component; and a texture pattern formed on said component or product. The acquiring means acquires, from the extracted n-dimensional-symbol image, the aforementioned information regarding the component or product. The identifying means identifies the component, product, or component-comprising product by matching image features of the extracted texture-pattern image against the image features stored by the image-feature storage. | 02-18-2016 |
