In this tutorial, we take a look at the term energy, as used in image processing. There are three different concepts of energy, in image processing, signal processing, and physics. All of them are closely related and we are going to focus on the part of image processing, shortly explainin...
an aspect ratio is the proportional relationship between an image's width and height. common aspect ratios include 4:3 (standard definition tv), 16:9 (high-definition tv), and 1:1 (square images). what is compression? compression is the process of reducing the size of an image file ...
PNG(pronounced ping) is the Portable Network Graphics file format for image compression. It provides several improvements over the GIF format. Like a GIF, a PNG file is compressed in a lossless manner, meaning that all image information can be restored when decompressing the file for viewing. P...
Video compression is the process ofencodinga video file in such a way that it consumes less space than the original file. Video compression makes it possible tostream videoover networks with limitedbandwidthand store large quantities of videodataondeviceswith limitedstorage. Video compressionalgorithmsc...
I am working on JPEG algorithm. After the dct step, the class is converted to double from unit8. In the zigzag step, the matrix is converted to an one dimensional array. I am confused now as how to get back the unit8 image class again after the compression? What do...
Image Compression ShortPixel takes care of your image compression needs “on the fly”, so it’s somewhat difficult to actually measure results. In fact, the only way to find stats on image compression is via their website. And you have to download a separate report that only updates once ...
exponents are used in algorithms for graphics rendering and image processing to perform operations like color transformations, blending, and filtering, enabling realistic and visually appealing visuals. how are exponents used in image compression to reduce file sizes? image compression algorithms like ...
Is JPEG compression too much, not enough, or just right? What exactly is “just right” anyway? This post will explore the concept of compression, why and how we do it, and how aggressive we should be in reducing the file size or increasing the image quality. ...
IQ tuning, or Image Quality tuning, is the process of adjusting various settings and parameters in a camera or image processing system to optimize the quality of the final image. This can include adjusting things like exposure, white balance, sharpness, and color saturation and often involves com...
The highest-quality images often start out as RAW files.DSLR camerascapture and hold image data in RAW files, which are typically large and highly detailed because there is no compression. Image generation software can sometimes create RAW files too, but this is less common. ...
