Digital Watermarking Using MATLAB

Digital Watermarking Using MATLAB

Embedding a hidden stream of bits in a file is called Digital Watermarking. The file could be an image, audio, video or text. Nowadays, digital watermarking has many applications such as broadcast monitoring, owner identification, proof of ownership, transaction tracking, content authentication, copy control, device control, and file reconstruction (Cox et. al., 2008). In literature, the host f...

Evaluation of the Digital images of Penaeid Prawns Species Using Canny Edge Detection and Otsu Thresholding Segmentation

Image segmentation is a key topic of research from many years. Image segmentation plays a very important role in computer vision .The purpose of image segmentation is to partition the image into an set of disjoint regions with the homogeneous and uniform attributes like intensity, tone, color and texture. Edge detection in images considerably reduces the amount of data and filters useless infor...

An Adaptive and Fast Valley Emphasis Multilevel Otsu Thresholding Algorithm

The multilevel thresholding problem is a challenge task due to the fact that the computation is usually very time-consuming for obtaining the optimal multilevel thresholds. Though the state-of-the-art multilevel thresholding algorithms applied various meta-heuristic techniques or acceleration strategies, they still directly searched the optimal thresholds in the whole histogram only for the fix...
