Shift-map image editing

Repairing Sparse Low-Rank Texture

“…In Figure 8, we present comparisons with Shift-Map method [19], Patch Match (PM) ( [18], [29]) and Structure Propagation (SP) [5] on four different images: a simulated non-uniform low-rank texture, a uniform building facade, [19], SP [5] and Photoshop [18]. Columns 1-2: input and result of our method; Columns 3-4: input and result of ShiftMap; Columns 5-6: input and result of SP; Columns 7-8: input and result of Photoshop.…”

“…For instance, they can not handle images with perspective deformation. In our method, the deformation can be estimated by solving (19). The estimated τ is then used to rectify the input region and we then solve (8) to repair the texture, typically with two iterations (first to estimate the error support, second to complete the image with a partially known error support).…”

“…In this experiment, we have conducted a series of comparative tests between our method and a few recent image completion methods such as the Shift Map (SM) method [19] and 3) is a checkerboard texture 91% randomly corrupted; second one (columns 4-6) is a real texture 30% corrupted on a disk like region; and third one (columns 7-9) is a real texture 40% corrupted by random blocks. In each case, the first image is input, the second is our result, and the third is result by RPCA [22].…”

“…Komodakis et al [4] treats image completion, texture synthesis and image inpainting in a unified manner by posing all of the above image-editing tasks in the form of a discrete global optimization problem. Many effective image completion systems are based such patch-based techniques, including Patch Match (PM) that used by Photoshop [18], Image Completion with Structure Propagation (SP) developed by Microsoft [5], and Shift Map (SM) [19].…”

Motion denoising with application to time-lapse photography

“…We, on the other hand, work in pixel resolution, supporting both small and irregular displacements. [14] perform geometric image rearrangement for various image editing tasks using a MRF formulation. Our work concentrates on a different problem and requires different formulation.…”
