Image Description Notes (with LSB encoding) by Michael Chan

The objective is to illustrate how certain reference may be made to a given image. (text, bit, data hiding)

Embedding/ Hiding Image Within Image (with LSB encoding) by Michael Chan

The objective is to illustrate how an image may be embedded or hidden within another given image. (bit, lsb, description)

Recovering data hidden in an image by Nithya V S

Recovers the text embedded using 'embedbp' in the Bth bit-plane of the input image, given the length (data hiding, watermarking, image processing)

Hiding data in an image by Nithya V S

Embeds the input data (text, or string) in the specified bit-plane of the input image and returns th (application, data hiding, image processing)
