In the analog world, photographic images have generally been accepted as ‘proof of occurrence’ of the depicted events. But today, the creation and manipulation of images is made simple by digital processing tools that are widely available and easily obtained. As a result, we can no longer take the authenticity of any images, analog or digital, for granted. This is especially true when they are ...

This paper is based on the study aimed at giving a new direction to Photographs, keeping in mind the growing needs of the people and enriching day-to-day experience vis-à-vis paper based photograph. A survey was conducted which revealed few startling but interesting facts as to what more the end-user wants than a mere ‘physical paper-based photograph’. This paper talks about the survey, respons...

Common tasks related to image processing or augmented reality include rendering new objects into existing images, or matching objects with unknown illumination. To facilitate such algorithms, it is often necessary to infer from which directions a scene was illuminated, even if only a photograph is available. For this purpose, we present a novel light source detection algorithm that, contrary to...

The contribution of this paper is a novel nonphotorealistic rendering (NPR) technique, influenced by the style of Cubist art. Specifically we are motivated by artists such as Picasso and Braque, who produced art work by composing elements of a scene taken from multiple points of view; paradoxically such compositions convey a sense of motion without assuming temporal dependence between views. Ou...

In this paper, we propose a method for selecting the most representative high-quality images from a set of user photographs. To avoid redundancy arising from many similar images, we find all sets of near-duplicates. We then rank images based on three technical qualities: exposure, blur, and contrast. Finally, we provide an ordering of the images which accounts for both quality and uniqueness. O...

BACKGROUND Hyperactivity of depressor septi nasi muscle leads to smiling deformity and nasal tip depression. Lateral fascicles of this muscle help in widening the nostrils. The purpose of this study was to evaluate the relationship between the nasal length changes and the alar base and the alar flaring changes during smile. METHODS Standard photographs are performed in the face and lat...
