Frame memory compression (FMC) is a technique to reduce memory bandwidth by compressing the video data to be stored in the frame memory. This paper proposes a new FMC algorithm integrated into an H.264 encoder that compresses a 4×4 block by differen

Set-partitioning in hierarchical trees (SPIHT) is a widely used compression algorithm for wavelet-transformed images. One of its main drawbacks is a slow processing speed due to its dynamic processing order that depends on the image contents. To over

Dynamic backlight scaling (DBS), a technique for LCD power reduction, often deteriorates image quality because of a flicker (unintended temporal variation of the luminance) generated in the frame at which the backlight level changes. This paper propo

Gabor filters are widely used to model the behavior of the V1 stage of the primary visual cortex of mammalian vision systems. Acceleration of this filter is critical for various real-time vision applications. In this work, we explore a variety of des

Biological vision systems use saliency-based visual attention mechanisms to limit higher-level vision processing on the most visually-salient subsets of an input image. Among several computational models that capture the visual-saliency in biological

This paper proposes a novel frame memory compression algorithm, called Pixel-Parallel SPIHT (PPS) that processes image data in parallel to increase the encoding throughput. The throughput of a PPS coder is an average of 4.48 bits per cycle which is 4

The SoC presented in this paper integrates an H.264 encoder with an ISP (Image Signal Processor). It is currently implemented in an FPGA and processes an HD-size (1280 × 720) image at the speed of 15 fps with the operating clock frequency of 50 MHz.

In order to use a synchronous dynamic RAM (SDRAM) as the off-chip memory of an H.264/AVC encoder, this paper proposes an efficient SDRAM memory controller with an asynchronous bridge. With the proposed architecture, the SDRAM bandwidth is increased b
