If the value if odd the binary bit is 1 else 0.PEP 545 – Python Documentation Translations | Following system colour scheme Selected dark colour scheme Selected light colour scheme Python Enhancement Proposals Every 3-pixels contain a binary data, which can be extracted by the same encoding logic. To decode, three pixels are read at a time, till the last value is odd, which means the message is over. Similarly, ‘ i‘ can be encoded in this image. Since we have to encode more data, therefore, the last value should be even. Now change the pixel to odd for 1 and even for 0.
Consider a 4 x 3 image with a total 12-pixels, which are sufficient to encode the given data. Since the message is of 3-bytes, therefore, pixels required to encode the data is 3 x 3 = 9. Suppose the message to be hidden is ‘ Hii ‘. The value is made odd if 1 occurs and even if 0 occurs. The first 8-values are used to store binary data. Now pixels are read from left to right in a group of 3 containing a total of 9 values.
