). Among them, BSP-15 is a high-efficiency DSP specially designed for video applications, with a highly integrated single chip to meet the needs of broadband products. At a clock frequency of 40 billion MHz, the BSP-15 processing capacity is 40 GOPS (8.5 integer operations per second), the processing speed is equivalent to 1.33 times of Pentium III, times of the

Computer vision is to make the computer understand the image and video, the purpose of this series of blog is to deepen their learning computer vision in the process of understanding and review of relevant knowledge. Many of the contents refer to: Textbook "Computervision:algorithms and Applications", textbook "Learning Image

Video information is provided by the front end data acquisition-->isp image processing-->scaler to the target image size-->encode--> sent to the user (e.g. TV can be displayed)Large amount of video data, more processing of

Why do I need to noise?Image Denoising is an important part and step in Digital image processing. The effect of denoising has a direct impact on the subsequent image processing, such as segmentation and edge detection. Image signa

To collect and process videos, you must learn to analyze YUV data. From the collection point of view, generally the video capture chip output streams are generally in the form of YUV data streams, while video processing (such as H. 264. MPEG Video Codec) is also used for encoding and parsing the original YUV code strea

If you need to compress a large video, there are many introductions on the internet, but all need to install a variety of video processing software, such as the format factory and so on. This article introduces a very handy little trick, without any video processing software

The image has many special effects algorithms, such as sketches, paintings, reliefs and so on. Video is also composed of a frame image, yes, these algorithms can be used for video, the video is first solved by frame, each frame is processed by the algorithm, and then re-enco
