Restoration of error-diffused images using projection onto convex sets
A novel inverse halftoning method is proposed to restore a continuous tone image from a given half-tone image. A set theoretic formulation is used where three sets are defined using the prior information about the problem. A new space-domain projection is introduced assuming the halftoning is performed using error diffusion, and the error diffusion filter kernel is known. The space-domain, freq...
متن کاملRestoration of error-diffused images using POCS
Halftoning is a process that deliberately injects noise into the original image in order to obtain visually pleasing output images with a smaller number of bits per pixel for displaying or printing purposes. In this paper, a novel inverse halftoning method is proposed to restore a continuous tone image from the given halftone image. A set theoretic formulation is used where three sets are defin...
متن کاملMesh Watermarking Using Projection onto Convex Sets
The current paper proposes 3D mesh watermarking using projection onto convex sets. As such, a 3D mesh is iteratively projected onto two constraint convex sets until the convergence condition is satisfied. The sets consist of a robustness set and invisibility set designed to embed the watermark. The watermark can be extracted without the original mesh using the decision values and index that the...
متن کاملRestoration of clipped seismic waveforms using projection onto convex sets method
The seismic waveforms would be clipped when the amplitude exceeds the upper-limit dynamic range of seismometer. Clipped waveforms are typically assumed not useful and seldom used in waveform-based research. Here, we assume the clipped components of the waveform share the same frequency content with the un-clipped components. We leverage this similarity to convert clipped waveforms to true wavef...
متن کاملDenoising Using Projection Onto Convex Sets (POCS) Based Framework
Two new optimization techniques based on projections onto convex space (POCS) framework for solving convex optimization problems are presented. The dimension of the minimization problem is lifted by one and sets corresponding to the cost function are defined. If the cost function is a convex function in R the corresponding set is also a convex set in R. The iterative optimization approach start...
