Scene recognition systems are generally based on features that represent the image semantics by modeling the content depicted in a given image. In this paper we propose a framework for scene recognition that goes beyond the mere visual content analysis by exploiting a new cue for categorization: the image composition, namely its photographic style and layout. We extract information about the im...

that refraction by a lens is not indispensable to the formation of a photographic image. The effective range of fluorescent and actinic X-rays is limited to two or three feet, and for this distance from a camera a "pinhole" in a metal disc does quite as well in ordinary photography as any lens or combination of lenses, so far as pictorial effect and clearness are concerned, provided the exposur...

With the tremendous development of computer graphic rendering technology, photorealistic computer graphic images are difficult to differentiate from photo graphic images. In this article, a method is proposed based on discrete wavelet transform based binary statistical image features to distinguish computer graphic from photo graphic images using the support vector machine classifier. Textural ...

Although photographic papers have been manufactured for at least as long as film has been made, there is little in the literature on their image microstructure properties. One of the earliest comprehensive experimental investigations of the “sharpness” (really the MTF) of photographic papers is that reported by Ruth Stapleton.1 One of the general conclusions of her work was that the Modulation ...

We discuss the obstacles to inference of correspondences between objects within photographic images and their counterpart concepts in descriptive captions of those images. This is important for information retrieval of photographic data since its content analysis is much arder than linguistic analysis of its captions. We argue that the key mapping is between certain caption concepts representin...

intermetallic phase formation and oxidation reaction during combustion synthesis (cs) of ni-ti equiatomic mixture are affected by mechanical activation (ma) and pre-heating conditions. important parameters are ignition time, reaction duration, temperature rise, microstructural change, titanium oxidation and intermetallic phase formation. superelasticity and shape memory effects are influenced b...

Photogrammetry uses photographic cameras to obtain information about the 3D world. The basic principle of photogrammetric measurement is straightforward: recording a light ray in a photographic image corresponds to observing a direction from the camera to the 3D scene point where the light was reflected or emitted. From this relation, procedures have been derived to orient cameras relative to e...

Statistical and Geometric Methods for Passive-blind Image Forensics Tian Tsong Ng Passive-blind image forensics (PBIF) refers to passive ways for evaluating image authenticity and detecting fake images. This dissertation proposes a physics-based approach for PBIF, with our definition of image authenticity derived from the image generative process comprising the 3D scene and the image acquisitio...
