imfuse works with grayscale or color image to average or subtract or color code two images. XORing two binary images tells where (what pixels) they are different. They're totally different things. 4 Comments Show 2 older comments char S on 18 Oct 2014...
For some reason, somewhere inside the project, a grayscale image is blurred using the function GaussianBlur. Even though the input images and all parameters are similar, the output is very different between the output that is obtained from the 3.3.0-version and the 4.7.0-version. I call ...
Bitmap is a monochrome pixel map; binary image data. Pixmap is a colorful pixel map; stores pixel colors. Difference Between Bitmap and Pixmap Table of Contents ADVERTISEMENTKey Differences Bitmap is an image file format used to store digital images independently of the display device, primarily...
The PNG compression algorithm is able to process true-color, grayscale, and palette-based types of images from 1-bit to 16-bit (unlike JPEG, which supports only the first two and only for 8 or 12 bits) Several choices of trade-off between compression ratio and speedPros...
before encryption so that the spatial correlation in the original image can be fully utilized. Yin et al. [24] compared the high bit-planes between the original pixels and its prediction value and labeled the successive same high bit-planes. The bit-plane labels are compressed by Huffman codin...

The Sobel operator optimized by local gradient enhancement performs edge detection on the grayscale image. The loss of local information can be reduced, and a better detection effect can be obtained. Using the Suzuki algorithm, the binary image contour obtained by the ES-MBD method can be detect...
superior performance and powerful generalizability in image fusion, they also have three considerable drawbacks: (1) Most multiscale transformation methods are inefficient in handling multilayer and multidirectional decomposition, as details of the source image can be lost during decomposition and ...
Assume that the quad block of the grayscale image I is shown in Figure 3a. Allow two thresholds, T1 = 2 and T2 = 10; the example of the embedding process is presented as follows: Figure 3. An example of a quad block for data embedding and extraction process. (a) Before embedding; ...
