Compress the image: if you choose a reasonable compression rate, the result will be indistinguishable from the original file, while its size will be significantly reduced. You can also resize the image, i.e., decrease its height and width. Modern cameras have much more pixels than your screen...
JPEGOptim, etc. The service did an impressive job at image compression. The resulting photo was reduced to 24% of the original size. According to the site, it’s possible to get a 90% file reduction. It can optimize JPEG, PNG, SVG, GIF, and WebP. ...
where \(\lfloor \rfloor\) indicates the floor function, which retrieves the highest integer less than or equal to a given input. 2. child (i; k): The node can own a maximum of 3 childrens in a \(3-ary\) heap. Therefore we can say, the manager may not manages more than 3 ...
In this paper, a novel image encryption algorithm based on the Once Forward Long Short Term Memory Structure (OF-LSTMS) and the Two-Dimensional Coupled Map Lattice (2DCML) fractional-order chaotic system is proposed. The original image is divided into se
Peak signal-to-noise ratio (PSNR): It is the ratio between highest intensity value in the image and the MSE. PSNR is expressed as (7.3)PSNR=20log10Imax2MSE. Here, Imax is the maximum pixel intensity in the image, i.e., 255 for gray level image. MSE and PSNR are widely adopted...

information but simply more information. This results in larger files than necessary and generally does not improve the quality of the image. On the contrary, it can even lead to worse images because each pixel will record less signal (i.e. lower signal-to-noise ratio or SNR,Pawley 2006)....
In this article, a novel image de-noising method is proposed. This method is based on spherical coordinates system. First, spherical transform is re-defined in wavelet domain, and the properties of the spherical transform in wavelet domain are listed. Th
