Leakage Reduction in WDR Image Sensors with Halftone Pixels

چکیده

Leakage reduction plays an important role in power consumption in many of the systems like image sensors. Adaptive bulk biasing control scheme is used to reduce the leakage during the standby mode of operation in the systems. Advanced WDR image sensors used to take images especially in situations where the light enters a premise from different angles, i.e. where both the dark and bright areas are there in the camera field of view that provides continuous tone images. Every pixel is to be converted in to halftone pixels in any of the conventional press, in order to print the image. Here a halftone pixel is generated using Floyd-Steinberg algorithm. The adaptive bulk biasing control scheme provides 21% power reduction as compared to any other standard systems.

پنهان نگاری وفقی براساس پیچیدگی نسبی پیکسلها در تصاویر دوسطح

In recent years steganography has attracted the attention of many researchers. Steganography can be used in media such as still image, audio, and video. Image is one of the most frequently used media. One of the forms of presentation of an image is halftone. In this paper a method is presented which hides data in halftone images. The data hiding process is performed during the halftoning step. ...

A secure authentication watermarking for halftone and binary images

Authentication watermark is a hidden data inserted into an image that can be used to detect any accidental or malicious alteration in the image. In the literature, there are many authentication-watermarking techniques for continuous-tone images. However, quite a small number of secure authentication watermarking techniques are available for binary/halftone images. This paper proposes a simple s...

Two Step Techniques for Image Compression

The image compression is the technique which is applied to reduce size of the original image. The image compression can be classified into lossy and loss-less type of compressions. The WDR is the lossy type of compression in which unwanted pixels will be removed from the image. In this work, improvement in the WDR algorithm is been proposed using the algorithm of decision tree. The decision tre...

Efficient fax transmission of halftone images

The efficient encoding and transmission of information for facsimile communication relies on redundancy in the scanned pixels. Halftone images, especiaily those rendered by high-quality dispersed dot techniques, are "busy" with alternative black and white pixels and shorter run lengths as compared to text information. Because of this, it is desirable to increase the redundancy and decrease the ...

Dispersed Error Control based on Error Filter Design for Improving Halftone Image Quality

The error diffusion method generates worm artifacts, and weakens the edge of the halftone image when the continuous gray scale image is reproduced by a binary image. First, to enhance the edges, we propose the edge-enhancing filter by considering the quantization error information and gradient of the neighboring pixels. Furthermore, to remove worm artifacts often appearing in a halftone image, ...
