Method and system for rescaling image files

Abstract

A system for resizing image files includes an FPGA including an interface controller operable to receive a plurality of image files through an interface, a computing kernel controller, and a memory controller. The FPGA also includes an interconnect coupled to the computing kernel controller and the memory controller and a plurality of computing kernels coupled to the interconnect. The system also includes a memory coupled to the FPGA.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method and a system for zooming and zooming an image compressed by the JPEG standard. The present invention is also applicable to scaling operations of other image compression formats than JPEG format. Background technique [0002] JPEG is the image format actually used in the Internet. Due to the explosion of social networks and Internet communications, a large number of images need to be transmitted every day, most of which are compressed using the JPEG standard. Due to the different screen resolutions and bandwidth capabilities of mobile devices such as tablets and smartphones and stationary devices such as desktops, images need to be resized for optimal viewing on each device. These image rescaling tasks are usually done in the data center. Data centers process it with large numbers of servers equipped with conventional microprocessors. Although data communication and proc...
