Watermark
The document proposes an image watermarking algorithm that is robust against geometric attacks. It embeds a watermark image into the medium frequency coefficients of the host image's wavelet domain. It extracts invariant centroids from the watermarked image to correct for geometric transformations like rotation and scaling. Experimental results showed the algorithm can withstand common signal processing and geometric attacks.
Scaling compression2
The document describes entropy scaling image compression. It reads in an 8-bit image file and creates 7 compressed versions by rounding pixel values to different bit depths from 8 to 2 bits. It displays the original and compressed images to show the effects of lower bit depth compression on image quality.

Comparison of image fusion methods
This document summarizes different techniques for fusing images from multiple sensors. It discusses how image fusion aims to reduce data volume while retaining important information. Single-sensor fusion involves fusing sequential images, while multi-sensor fusion overcomes single-sensor limitations. Key steps in image fusion systems include registration, preprocessing, and postprocessing. Common fusion methods discussed are in the spatial domain (e.g. weighted averaging, Brovey transform) and transform domain (e.g. discrete wavelet transform). The document evaluates different fusion methods for applications like remote sensing and medical imaging, finding the multiresolution analysis-based intensity modulation method most accurately reproduces high-resolution images.

Wavelet
The document discusses performing a discrete wavelet transform (DWT) on a 1D signal using MATLAB. It loads a test signal, performs a 5-level DWT decomposition using the coif3 wavelet, then reconstructs the approximation and detail signals at each level. Plots of the original, approximation, and detail signals are generated.
Wavelet watermark level3
The document discusses adjusting damage resolution on an image and improving a watermark by applying a Gaussian filter. It also mentions displaying the image at level 2.
Wavelet watermark level2
This document describes a watermarking algorithm that embeds a watermark into an image using discrete wavelet transforms. It performs a 2-level discrete wavelet transform on the image and watermark. It then adds a scaled version of the watermark coefficients to the image coefficients if they exceed a threshold. The inverse discrete wavelet transform is applied to get the watermarked image. It also describes how to detect the watermark by filtering the watermarked image and subtracting the original, then applying wavelet transforms to the difference.
Two dimensional true wavelet compression
The document discusses image compression techniques. It introduces compression goals of minimizing file size while maintaining quality. It then covers compressing grayscale images using global thresholding and Huffman encoding. The document demonstrates this method on a "mask" image, outputting the compression ratio and bits per pixel. It also covers compressing color images using wavelet-based methods like SPIHT. The quality of the compressed "wpeppers" image is assessed using MSE and PSNR metrics.
Image fft
This document discusses taking the Fourier transform of an image containing lines, shifting the transform so that low frequencies are at the center, and removing some of the Fourier coefficients around the edges to reconstruct the image while filtering out some high frequency information. It loads an image, takes its Fourier transform, shifts it, and removes coefficients outside a central region before taking the inverse Fourier transform and displaying the reconstructed image.
Image dct shifting
This document summarizes work done to properly apply the discrete cosine transform (DCT) to an image. It was found that shifting pixel values by 128 before applying the DCT was necessary to avoid negative DC coefficient values after reconstruction. Using integer 16 data type for the image instead of uint8 helped preserve pixel values below 128 after reconstruction. Not shifting the data led to incorrect pixel values being lost during reconstruction.
Tcp snoop protocols
The document describes the Snoop+α protocol, which improves on the Snoop protocol. The Snoop+α agent monitors ACKs passing through the access point and categorizes them as duplicate, spurious, or new. This allows it to detect packet loss without duplicate ACKs and retransmit lost data locally instead of waiting for the fixed host. The protocol provides end-to-end TCP connections while improving performance and reducing delay compared to plain wireless networks.
