- Irrelevance reduction and redundancy reduction are two sub-steps of the seven-step JPEG compression process. When it comes to this topic, clarify the distinction between redundancy and irrelevance reduction.JPEG compression What exactly is converted from which format to which format during color model conversion in the JPEG encoding process?2a) Describe with the aid of a schematic diagram about the JPEG Encoder.
- a) Elaborate the frame types in video compression. b) Explain the Motion compensation technique in Video compression.An image is to be compressed using JPEG compression that uses 4x4 blocks instead of 8x8 blocks. The remaining compression steps remain unchanged.

- 1. MPEG output consists of three kinds of frames – I, P, and B frames. For scenes in which the camera and background are stationary and one or two actors are moving around slowly, nearly all the pixels will be identical from frame to frame. Here, just subtracting each frame from the previous one and running JPEG on the difference would do fine. However, for scenes where the camera is panning or zooming, this technique fails badly. Let us assume that the background of scenes is stationary, and the scenes are sent on UDP. Due to an unreliable communication, UDP may loss some of the frames. Which frame (I, P or B) is significant? Thank you so much in advance.You have an image with 640 x 480 pixels in 24-bit RGB colour to be compressed by using the JPEG method. Calculate the size of the image in the RGB model and in the YCÜC model with 4:2:0 chrominance subsampling. Determine the compression ratio of this chrominance subsampling.Many copies of a video may be made with different quality levels using compression methods. What are you attempting to accomplish with this?
- Let æ(n1, n2) represent an 8x8 luminance block. The DCT of r(n1, n2) is quantized using the JPEG luminance quantization Q matrix as specified in Section K, Table K.1, of the ISO/ITU-T JPEG standard document that is provided on the course web site. The resulting quantized DCT of a(n1, n2) is given by: 128 10 0 ... -4 0 ... X4(K1, K2) = 0. ... 0 0 ... which contains only three non-zero coefficients. (a) Using Table F.2 (page 90) and Table K.5 (pages 150 to 153) of the ISO/ITU-T JPEG standard document that is provided on the course web site, determine the JPEG bit stream for the AC coefficients. (b) What is the average bit-rate associated with these coded AC coefficients (in bits/coefficient)? (c) What is the JPEG bit-stream of the considered 8 x 8 block if the quantization Q matrix is a constant matrix where each element is equal to 3000?What is the size of an (uncompressed) RGB image with no transparency with 4K resolution (3840 x 2160 pixels)? What will the size be in monochrome (binary)?PEG compression The seven steps of JPEG compression can be divided into irrelevance reduction and redundancy reduction. In this context, explain what is meant by redundancy reduction and irrelevance reduction respectively and what the difference is.
