WebMar 22, 2024 · The EEG data compression scheme consists of a combination of two algorithms: agglomerative hierarchal clustering and Huffman encoding. First, the received EEG data is clustered into clusters. Then, the Huffman encoding is applied to each resulted cluster in the second phase. Finally, the compressed files of smaller clusters are … WebJul 22, 2024 · In video compression, the frame is divided into blocks that have the size from 4*4 to 64*64. An image compression technique — JPEG [3] divides the image into blocks 8*8. After that, the two-dimensional Discrete Cosine Transform (DCT) is applied to each of these 8×8 blocks. Equation (1) is the DCT function.
