![]() ![]() It uses an English dictionary and a word replacing transform. I wrote my own code for detecting and transforming natural language text. ![]() The preprocessor uses separate components for detecting the type of data and actually doing the transformation.įor images and binary executables, I used code for detection and transformation from the open source paq8pxd program. Architecture PreprocessingĬmix uses a transformation on three types of data: The output of the context mixer is refined using an algorithm called secondary symbol estimation (SSE). The model predictions are combined into a single probability using a context mixing algorithm. cmix generates a probabilistic prediction for each bit and the probability is encoded using arithmetic coding.Ĭmix uses an ensemble of independent models to predict the probability of each bit in the input stream. This data is then compressed using a single pass, one bit at a time. The preprocessing stage transforms the input data into a form which is more easily compressible. Most of the ideas I implemented came from the book Data Compression Explained by Matt Mahoney. I started working on cmix in December 2013. Silesia Open Source Compression Benchmark File Silesia Open Source Compression Benchmark.The compressed size can vary slightly depending on the compiler settings used to build the executable. GitHub repository: Downloads Source CodeĬompression and decompression time are symmetric. Feel free to contact me at if you have any questions. At least 32GB of RAM is recommended to run cmix. cmix is free software distributed under the GNU General Public License.Ĭmix works in Linux, Windows, and Mac OS X. It gets state of the art results on several compression benchmarks. The app is cute, works well, and lets you expand and preview uploaded images (before compression), to make sure the configured parameters are the right ones for the compression/resizing job you are about to start.Cmix is a lossless data compression program aimed at optimizing compression ratio at the cost of high CPU/memory usage. In conclusion, Image Compressor is surely a software solution that can do both image compression and resizing for you well and fast. Also, for each image, the program will display the output's expected file size and resolution. When setting up the image compression parameters, you can choose to compress images by a given percentage or with a user-input ratio, as well as set up the file output quality with a percentage-indicator slider.įurthermore, you can add multi-format images in one go and submit all of them for batch compression and/or resizing.Īfter uploading your images into the application, you can start processing them individually or in bulk. In one go, you can choose the name format of your outputs, ignore uploaded images that are under a certain file size, and preview your files. Plus, the app's one-layout interface is suitable for those who want to easily process images without much hassle. With Image Compressor, you can add and process PNGs, JPGs, WEBPs, and GIFs. ![]() Supported formats, batch processing, and other features The tool lets you switch to a dark theme, drag and drop images into its queue compression list, configure the files' output name, and easily set up the compression and resizing parameters. ![]() At the same time, the progam has a unique-design interface, with a colorful implementation. The tool runs smoothly, and it is compatible with 64-bit system architectures only. Image Compressor is an open-source project. Getting started with this image compressing app Image Compressor gives users access to image compression and resizing capabilities at no cost, in a pretty-looking interface, all with various output modification options and batch image processing capabilities. ![]()
