A Review on Various Image and Video Restoration Techniques
Abstract: Reconstruction of low value deteriorated image into high quality improved image is termed as image restoration. The sight of this paper is to have knowledge about mixed restoration techniques like, average filter, median filter, wiener filter, blind de-convolution, and wavelet transform etc. The basis of restoration is to undo the operation of degraded image. There are many grounds because of which degradation takes place like, poor weather conditions, camera misfocus, …

Inpainting an Image based on Enhanced Resolution
Abstract: AbstractInpainting is the measure of reconstructing damaged parts of images. The main goal of inpainting is to remove unwanted objects from images and fill this region with the background. At first a part of the input image is inpainted by a non-parametric patch sampling. The inpainted part of the input image allows reducing the computational complexity and less sensitive to noise. The advantage is it is easier to inpaint low …

A Simple PN Sequence Based Steganography for Images: Spatial Domain and DCT Domain Performances
Abstract: Image steganography is the art of hiding a secret image into another image, called a cover image. Secret image which is converted to a 1D vector is embedded to the cover image. The embedding mechanism is simply adding the bit. In spatial domain, each bit is added to theselected pixel values. The selection is based on a PN sequence generated. Similarly, in DCT domain, based on PN sequence, DCT coefficients …

Image Inpainting Techniques Comparative Analysis for the Amputation of Smearing Effects from the Inpaint Image
Abstract: Image inpainting is the process to reconstruct the missing or damaged portions of the image, in order to make it more legible and restore its unity. This can be done by using information from adjoining areas and amalgamate the inpainted area into the image so impeccably that a typical viewer is not aware of it. The eminence of the upshot will depend on what is omitted. If the inpainting region …

Proposed Algorithm for Shadow Identification and Classification in VHR Satellite Imagery
Abstract: The Very High Resolution (VHR) satellite imagery offers great possibilities for urban environments. Unfortunately, shadows cast by buildings in high-density urban environments obscure much of the information in the image, leading to potentially corrupted classification results or blunders in interpretation. The objective of this paper is to propose an algorithm for better identification and classification of shadows in VHR images. Two prime stages were carried out i.e. shadow identification and …

External Filtering and Wavelet Domain Thresholding-based Denoising Method for AWGN corrupted imagesExternal Filtering and Wavelet Domain Thresholding-based Denoising Method for AWGN corrupted images
Abstract: In this work an image de-noising method with external bilateral filtering and wavelet domain thresholding has been proposed. In Gaussian filtering, it fails to denoise an image at edges where the spatial variations are not smooth and causesblurs at the edges in the image. External bilateral filter (EBF) beats this by filtering the picture in both reach and area (space). Respective separating is a nearby, nonlinear and non-iterative procedure which …

Comparative Study of Structure-from-Motion Algorithms 3D Shape Reconstruction
Abstract: 3D shape reconstruction from multiview photographs and video sequences (2D images) is an active area of research. Existing face recognition systems are based on 2D facial images and exhibit well-known deficiencies. Accordingly, the face recognition research is gradually shifting from classical 2D to sophisticated 3D or hybrid 2D/3D. Currently the 3D reconstruction algorithms may be grouped in to four categories. These are shape-from-X, 3D morphable model (3DMM), structure from motion …

Towards the Development of Low Cost Calibration Apparatus for 3D Reconstruction of Spine
Abstract: Three-dimensional reconstruction of the human spine is very much essential in diagnosis, planning of surgery and treatment of several spinal deformities. This can be achieved using stereo-radiographic methods. Calibration of a stereo-radiographic setup is a necessary step in this process. It provides metric information from 2D images. Many calibration methods that are available in literature result in cumbersome calibration objects. Hence difficult to use in the clinical valuation of spinal …
