GigE Vision GigE Vision is a standard for connecting Camera to Frame Grabber build upon existing Ethernet technology.It has two main parts namely: GigE Vision Control Protocol (GVCP) that allows the configuration of detected drivers and guarantees transmission reliability. The GigE Vision Streaming Protocol (GVSP) that allows applications to receive video data stream from Camera. … Read more
SD SDI & HD SDI SDI includes low resolution SD-SDI (SMPTE 259) and HD-SDI (SMPTE 294). SD-SDI is used to transmit low resolution PAL compatible video 720 * 576 @ 25fps and uses a clock rate of 27 MHz. HD-SDI is used to transmit HD video including 720-P and 1080-I using a 10 bit 148.5 … Read more
Camlink Interface Channel Link consists of a driver and receiver pair. The driver accepts 28 single-ended data signals and a single-ended clock. The data is serialized 7:1, and the four data streams and a dedicated clock are driven over five LVDS pairs. The receiver accepts the four LVDS data streams and LVDS clock, and then … Read more

Video Acquisition System The system is targeted to enhance the quality of the videos from the thermal imagers system and equip the imagers with the capability of video acquisition, video streaming and video analytics. Video Capturing Unit and Video Processing Unit will be implemented in the PL portion of the FPGA. These units will be … Read more
Video captured from thermal imaging systems, hand-held camcorders is typically jerky due to small, unwanted camera movements. Video stabilization techniques are used to generate a stabilized video sequence by modeling the undesirable camera movements and eradicating from the input video sequence. The Video Stabilization System is an embedded solution using one of such techniques. The … Read more
Bi-lateral Filter Latest research in the field of image processing has shown that the bilateral filter is one of the most popular filters designed for noise suppression while preserving edges at the same time. The Input Video Data Buffer reads the data from the source and provides a pixel array of configurable kernel size to … Read more
Nor Flash Controller The NOR flash controller performs flash programming through SPI interface. Mainly, four operations such as read, write and erase and reset are required to program Serial NOR flash memory. The controller consists of a dedicated state machine in order to execute these operations and a SPI master which serially sends data to … Read more
Nand Flash Controller The NAND flash controller mainly performs four operations such as memory read, write and block erase and memory reset. The controller consists of a dedicated state machine in order to execute these operations and a low level interface block which is used to generate a pulse of fixed width. Each FSM receive … Read more
