| Summary: | To print ceaseless tone images, Electrophotographic printers mostly use halftoning method. Scanned pictures procured from such hard transcripts are generally wrecked by screen like antiquities. Recently an approach for reviving relentless image from scanned halftone picture was accomplished. This new model considers both printing deformities and halftone motifs. At first denoising computation is proposed to evacuate printing noise and then, Screen Frequency of scanned halftone picture is estimated and Local Gradients are calculated. Next, Gaussian Filter whose variable are dynamically adapted is exerted to compute basic persistent tone value of each pixel and diminish twists. At the end, Edge- Sharpening technique is propounded to shield edges of checked picture. Finally descreened Scanned images with unremitting tones are acquired. In this paper this technique is extended for color scanned halftone images. Demonstrations show that the proposed method can recuperate perpetual tone pictures from the real scanned facsimile. |
