tems for digital cinema‚ projectors‚ and playback video servers have been commercialized based on the standards issued by the Digital Cinema Initiative (DCI). 8K is the SHD video format defined in DCI specification. It has a resolution of 4096 2160 pixels‚ so its image qual- ity is equivalent to that of 35-mm film. The total bit rate of raw 8K videos with the frame rate of 24 frames/s is about 7 Gb/s. This necessitates the use of the JPEG2000 algorithm to compress the bit rate to 250 Mb/s. To deliver

advantages and disadvantages respectively. Raster images are complex renderings made up of thousands of little dots or pixels. The word raster has its origin in Latin which means ‘rake’ and has come to refer to a rectangular pixilated grid. Photograph editors like Adobe Photoshop‚ Corel Photo-Paint‚ Corel Paint Shop Pro and The GIMP are great to manipulate each pixel. Many will argue that this type of graphic deals more practically for photo-realistic images. Raster graphics depend highly

Vector graphics is the use of geometrical primitives such as points‚ lines‚ curves‚ and shapes or polygon(s)‚ which are all based on mathematical expressions‚ to represent images in computer graphics. "Vector"‚ in this context‚ implies more than a straight line. Vector graphics are based on images made up of vectors (also called paths‚ or strokes) which lead through locations called control points. Each of these points has a definite position on the x and y axes of the work plan. Each point‚ as

When JPG files are saved‚ they use "lossy" compression‚ meaning image quality is lost as file size decreases. M1: A raster graphic or image is made up of pixels. Pixels are small squares of information. Raster graphics are wonderful for rich‚ full-colour images such as photographs. Raster graphics are rendered images on a pixel-by-pixel basis and they are fantastic when handling shading
