This paper presents an automatic image alignment algorithm that alleviates the need to keep the camera still during the capture of a bracketed sequence to obtain an HDR image. Our algorithm assumes that the misalignment between the two consecutive exposures is translational. Using a photographically guided random search, our algorithm first finds properly exposed high contrast regions. The shift amount is then found by analyzing and matching the pixel correlations inside these regions.

Error analysis and testing of DRM for frame cameras Bettemir, Oe. H.; Karslıoğlu, Mahmut Onur; Friedrich, J. (2007-06-16) A new Differential Rectification Method (DRM) for frame cameras is proposed by Karslioglu and Friedrich [1] for the generation of orthoimages from monoscopic digital images which map every pixel onto a curved surface of reference frame i.e. WGS84. The ellipsoidal geodetic coordinates, of each pixel are calculated directly under the condition that a precise enough elevation model is available avoiding additional earth curvature corrections after the rectification. In this paper, convergence of the differenti...
Cognitive aspects of image zooming Öncül, Gaye; Tarı, Sibel; Tekman, Hasan Gürkan; Department of Cognitive Sciences (2002) In this work, digital image zooming methods and image distortion metrics are examined in terms of a quality criterion based on image appearance. Neurophysiological and psychophysical foundations of perception driven image distortion metrics are presented. Results of a comparative study based on both perceptual distortion metrics and conventional distortion metrics for standard zooming methods are discussed. Open problems in image quality definition as well as image enlargement methods are presented and impr...
Privacy protection of tone-mapped HDR images using false colours ÇİFTÇİ, Serdar; Akyüz, Ahmet Oğuz; PİNHEİRO, Antonio M. G.; Ebrahimi, Touradj (2017-12-01) High dynamic range (HDR) imaging has been developed for improved visual representation by capturing a wide range of luminance values. Owing to its properties, HDR content might lead to a larger privacy intrusion, requiring new methods for privacy protection. Previously, false colours were proved to be effective for assuring privacy protection for low dynamic range (LDR) images. In this work, the reliability of false colours when used for privacy protection of HDR images represented by tone-mapping operators...
Iterative Photometric Stereo with Shadow and Specular Region Detection for 3D Reconstruction BUYUKATALAY, Soner; BİRGÜL, ÖZLEM; Halıcı, Uğur (2009-04-11) Photometric stereo is a 3D reconstruction algorithm that uses the images of an object with different light conditions and its performance is affected by the shades and specular regions in the images. Especially, the use of Lambert reflectance model results in errors in the reconstructed surface normals. In this study an iterative approach was used to generate masks corresponding to these problematic regions and the surface normals were reconstructed using a Lambert based algorithm that excludes these region...
Image fusion for improving spatial resolution of multispectral satellite images Ünlüsoy, Deniz; Süzen, Mehmet Lütfi; Department of Geological Engineering (2013) In this study, four different image fusion techniques have been applied to high spectral and low spatial resolution satellite images with high spatial and low spectral resolution images to obtain fused images with increased spatial resolution, while preserving spectral information as much as possible. These techniques are intensity-hue-saturation (IHS) transform, principle component analysis (PCA), Brovey transform (BT), and Wavelet transform (WT) image fusion. Images used in the study belong to Çankırı reg...
