A pixel circuit for CMOS active sensor imaging applications is presented. An in-pixel open-loop voltage amplifier achieves efficient bandwidth limitation using low capacitance values, and it allows excellent reduction of downstream readout circuit noise, t ...
Memory colours refer to the colour of specific image regions that have the essential attribute of being perceived in a consistent manner by human observers. In colour correction-or rendering-tasks, this consistency implies that they have to be faithfully r ...
NOVELTY - The method involves illuminating an object i.e. aneurysm, with measuring light with wavelengths ranging from 790 nanometer to 820 nanometer, and recording a sequence of images (21, 22) i.e. white light image, of the illuminated object. The sequen ...
In the last decades, image production has grown significantly. From digital photographs to the medical scans, including satellite images and video films, more and more data need to be processed. Consequently the number of applications based on digital imag ...
JPEG XR is the newest image coding standard from the JPEG committee. It primarily targets the representation of continuous-tone still images such as photographic images, and achieves high image quality, on par with JPEG 2000, while requiring low computatio ...
A modification to the standard Bayer CFA and photodiode structure for CMOS image sensors is proposed, which we call 2PFC™, meaning “Two Pixel, Full Color”. The blue and red filters of the Bayer pattern are replaced by magenta filters. Under each magenta fi ...
Embodiments of the present invention recite a system and method for conveying the true color of a subject. In one embodiment, the present invention comprises an image capture device, an imaged reference color set comprising at least one reference color, an ...
This paper presents a novel rate allocation scheme to compute the 3D structure of the scene from compressed stereo images, captured by the distributed vision sensor networks. The images captured at different view points are encoded independently with a bal ...
Skin tone images, portraits in particular, are of tremendous importance in digital photography, but a number of factors, such as pigmentation irregularities (e.g., moles, freckles), irritation, roughness, or wrinkles can reduce their appeal. Moreover, such ...
The contribution of this paper is two-fold. First, we show how to extend the ESM algorithm to handle motion blur in 3D object track- ing. ESM is a powerful algorithm for template matching-based tracking, but it can fail under motion blur. We introduce an i ...
