WebHuffman Tree. Step 1: For each character of the node, create a leaf node. The leaf node of a character contains the frequency of that character. Step 2: Set all the nodes in sorted order according to their frequency. Step 3: There may exist a condition in which two nodes may have the same frequency. WebHuffman coding is based on the frequency of occurance of a data item (pixel in images). The principle is to use a lower number of bits to encode the data that occurs more frequently. Codes are stored in a Code Book which may be constructed for each image or a …

WebFor example, the Huffman code for the probability distribution P4 = (0.45, 0.25, 0.2, 0.1) is constructed as follows. We first combine the two smallest probabilities to obtain the probability distribution (0.45, 0.25, 0.3) which we reorder to get P3 = (0.45, 0.3, 0.25).
