Some embodiments provide a method of aligning a pair of images. The method defines multiple different pairs of images at multiple different resolutions. The method hierarchically aligns the original pair of images by first aligning the pair of images at the lowest resolution and then aligning each pair of images at each higher resolution based on the alignments of the pair of images at the lower resolutions. For some of the resolutions, to perform the hierarchically alignment, the method identifies, for at least one image at each resolution, portions that are suitable for performing the alignment and portions that are not suitable for performing the alignment. The method compares each pair of images at a particular resolution by using the suitable portions while excluding the unsuitable portions from the comparison.

Some embodiments provide a method of operating a device to capture an image of a high dynamic range (HDR) scene. Upon the device entering an HDR mode, the method captures and stores multiple images at a first image exposure level. Upon receiving a command to capture the HDR scene, the method captures a first image at a second image exposure level. The method selects a second image from the captured plurality of images. The method composites the first and second images to produce a composite image that captures the HDR scene. In some embodiments, the method captures multiple images at multiple different exposure levels.

An omnidirectional video camera captures images of the environment while moving along several intersecting paths forming an irregular grid. These paths define the boundaries of a set of image loops within the environment. For arbitrary viewpoints within each image loop, a 4D plenoptic function may be reconstructed from the group of images captured at the loop boundary. For an observer viewpoint, a strip of pixels is extracted from an image in the loop in front of the observer and paired with a strip of pixels extracted from another image on the opposite side of the image loop. A new image is generated for an observer viewpoint by warping pairs of such strips of pixels according to the 4D plenoptic function, blending each pair, and then stitching the resulting strips of pixels together.

A bridge local damage identification method based on an influence line under a structure health monitoring system relates to the field of engineering structure health monitoring. The method comprises the following steps: (1) fast identification of a bridge influence line; (2) construction of influence line damage indexes; and (3) damage identification based on fusion of multi-sensor information. A bridge influence line is identified based on moving vehicles and bridge response monitored in real time by a bridge health monitoring system, the change of the influence line can be captured in a timelier and quicker way, and structure abnormality can be found early. Based on the fact that the damage indexes of the influence line are more sensitive to local damage of long-span bridges and less sensitive to the change in environmental factors, the method is more applicable to detection of local damage of long-span bridges in an operating environment. By combining the multi-sensor information fusion theory and the influence line damage indexes, the anti-noise-interference and damage locating abilities of the damage identification method are improved greatly, and the credibility of damage decision is improved.
