Systems and methods are described for measuring the quality of telephone transmission lines. The filter includes a hub disposed along a longitudinal axis and a plurality of anchor members extending from the hub. A long handle may project up from the tool body with a large aperture just above the tool body into which the user’s foot may be placed to help in pushing the projections into the ground to make holes sized for planting garden plants. The method also includes identifying image data in the second image that is not associated with a valid offset value, generating a supplementary offset value using valid offset values associated with image data substantially near the image data in the second image, and associating the image data in the second image with the supplementary offset value. An alternative approach may involve performing a multi-resolution decomposition of all the captured images, using temporal fusion, spatio-temporal fusion, or combinations thereof, at each level and combining the different levels to generate an output image.
