The main constrained problem of the video monitoring and storage system is the contradiction between large field of view and storage space limitations. Not all of the video information introduced by the image sensors need to be recorded especially for some tracking system which has appointed functions to track specifically kinds of targets. For instance
the system not only works for single target
if the monitor is appointed for human face tracking
but also can work for multi-targets. High reconstruction resolution in the fovea region enables the successive application of recognition modules without sacrificing their performance
the best system appears to be concentrating on human face only and all the others considered being background
the low reconstruction resolution in the periphery helps to reduce the video data. 2010 IEEE.
the background regions needn't to be recorded in detail. For this purpose
this letter presents a real-time foveate storage system
which efficiently represents the video image in log-polar coordinates
with the foveate point centered on the target

This paper presents an intelligent video surveillance system. The system is composed of one or more nodes flexibly according to the application scenarios such as private properties
banks and museums. Each node is an autonomous vision-based device capable to perform intelligent tasks. It is able to digitize and compress the acquired analog video signals in MPEG-4 standard and then transmit the compressed video stream to the control center. At the same time
the node makes use of a statistical approach for real-time detecting moving object and online alarm generation to enable a single human operator to monitor activities over a complex area using a distributed network of active video sensors. The node is implemented on a platform with high performance to ensure that the algorithm is able to run in real-time. Applications demonstrate that the intelligent system has an excellent performance in many scenarios to help people make decisions more accurately and rapidly. 2010 IEEE.

In current field of CCD measurement
large area and high resolution CCD is used to obtain big measurement image
so that
speed and capacity of CCD requires high performance of later storage and process system. The paper discusses how to use SCSI hard disk to construct storage system and use DSPs and FPGA to realize image compression. As for storage subsystem
Because CCD is divided into multiplex output
SCSI array is used in RAID0 way. The storage system is composed of high speed buffer
DMA controller
control MCU
SCSI protocol controller and SCSI hard disk. As for compression subsystem
according to requirement of communication and monitor system
the output is fixed resolution image and analog PAL signal. The compression means is JPEG2000 standard
in which
9/7 wavelets in lifting format is used. 2 DSPs and FPGA are used to compose parallel compression system. The system is composed of FPGA pre-processing module
DSP compression module
video decoder module
data buffer module and communication module. Firstly
discrete wavelet transform and quantization is realized in FPGA. Secondly
entropy coding and stream adaption is realized in DSPs. Last
analog PAL signal is output by Video decoder. Data buffer is realized in synchronous dual-port RAM and state of subsystem is transfer to controller. Through subjective and objective evaluation
the storage and compression system satisfies the requirement of system. 2009 SPIE.
