Validation for Visually Lossless Compression of Stereo Images
نویسندگان
چکیده
This paper described the details of subjective validation for visually lossless compression of stereoscopic 3 dimensional (3D) images. The subjective testing method employed in this work is adapted from methods used previously for visually lossless compression of 2 dimensional (2D) images. Confidence intervals on the correct response rate obtained from the subjective validation of compressed stereo pairs provide reliable evidence to indicate that the compressed stereo pairs are visually lossless.

Lossless Microarray Image Compression by Hardware Array Compactor
Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...
متن کاملPerceptual Image Compression Using Jpeg2000
Image sizes have increased exponentially in recent years. The resulting highresolution images are typically encoded in a lossy fashion to achieve high compression ratios. Lossy compression can be categorized into visually lossless and visually lossy compression depending on the visibility of compression artifacts. This dissertation proposes visually lossless coding methods as well as a visually...
متن کاملRegion-based method for visually lossless image compression
This report proposes a new method for image compression. The compressed images are visually identical to the originals, even though some of the information in the images is discarded. This is achieves by using results in the field of Human Vision Modeling to select the visually significant regions from the images. Two different compression methods are applied, depending on whether the compresse...
متن کاملBlock-based segmentation and adaptive coding for visually lossless compression of scanned documents
This paper presents a novel block-based segmentation and adaptive coding(BSAC) algorithm for visually lossless compression of scanned documents that contain not only photographic images but also text and graphic images. For such compound image source, we structure the image into nonoverlapping blocks and classify each block into four different classes based on the empirical statistics within th...
متن کاملVisually Lossless Compression Based on Jpeg2000 for Efficient Transmission of High Resolution Color Aerial Images
Aerial image collections have experienced exponential growth in size in recent years. These high resolution images are often viewed at a variety of scales. When an image is displayed at reduced scale, maximum quantization step sizes for visually lossless quality become larger. However, previous visually lossless coding algorithms quantize the image with a single set of quantization step sizes, ...
