I have a basic implementation knowledge of the 2D 8x8 DCT used in image & video compression. Whilst reading about Principle Component Analysis, I can see a lot of similarity, albeit PCA is clearly ...
Hi I'm preparing for my exam tomorrow and I've come across a 17 Mark question which seems trivially easy, so I think I'm missing a key point giving the rest of this exam is fairly difficult. The ...
I'm doing practice exam questions for my multimedia systems exam one tuesday and a topic which seems to come up frequently is the appropriate use of encoding B-frames based on: 1) the previous I or ...
I am wondering what would be the right approach to extract top and bottom fields from a YUV 4:2:0 frame. In the YUV 4:2:0 representation, Luma and Chroma samples are located as shown below: Y Y Y Y ...
I am looking for a low MIPS, low compression video encoder. This is for a 10fps, VGA type quality compression. What are my options? I need to be able to do this compression using a 150MHz ARM M4 CPU ...
Extremely computationally intensive image/video compression schemes which offer better compression than industry standard JPEG/H.264
I am trying to search for image/video compression schemes which offer superior compression performance (holding image quality as constant) when compared to widely adopted industry standards (i.e. ...
In MPEG, there is a process where an image is broken up into macroblocks and a motion vector is computed for each of those macro blocks. You then transmit these vectors, along with the prediction ...
