Big Data Compression Using Anamorphic Stretch Transform
نویسندگان
چکیده
The proliferation of image data is a major contributor to the big data and the problems associated with its storage and transmission. In this paper, we present applications of the recently introduced Anamorphic Transform to enhancing the performance of two popular image compression methods, JPEG and JPEG 2000. The transformation increases the spatial coherence resulting in superior compression without sacrificing the image quality. We present examples showing improved compression of various types of images contributing to big data including medical, security and surveillance, astronomy, and satellite images.

A Survey on Image Compression Techniques
Medical images are compressed before storage and transmission because of the bandwidth and storage limitations. After compression the redundancy and irrelevance of image data is reduced without affecting the quality of the image. The compression of images allows more images to be stored memory. The time required to send the images over the internet and download from the web pages are also be re...
متن کاملAnamorphic transformation and its application to time-bandwidth compression.
A general method for compressing the modulation time-bandwidth product of analog signals is introduced. As one of its applications, this physics-based signal grooming, performed in the analog domain, allows a conventional digitizer to sample and digitize the analog signal with variable resolution. The net result is that frequency components that were beyond the digitizer bandwidth can now be ca...
متن کاملOptical Data Compression in Time Stretch Imaging
Time stretch imaging offers real-time image acquisition at millions of frames per second and subnanosecond shutter speed, and has enabled detection of rare cancer cells in blood with record throughput and specificity. An unintended consequence of high throughput image acquisition is the massive amount of digital data generated by the instrument. Here we report the first experimental demonstrati...

We introduce “anamorphic” cosmology, an approach for explaining the smoothness and flatness of the universe on large scales and the generation of a nearly scale-invariant spectrum of adiabatic density perturbations. The defining feature is a smoothing phase that acts like a contracting universe based on some Weyl frame-invariant criteria and an expanding universe based on other frame-invariant ...
متن کاملDesign of Warped Stretch Transform
Time stretch dispersive Fourier transform enables real-time spectroscopy at the repetition rate of million scans per second. High-speed real-time instruments ranging from analog-to-digital converters to cameras and single-shot rare-phenomena capture equipment with record performance have been empowered by it. Its warped stretch variant, realized with nonlinear group delay dispersion, offers var...
