Questions tagged [Data compression] (32)

Have long been interested in coding with compression. And since we do neural networks and genetic algorithms, the question arises, what are the prospects of using them for compression. Found on the Internet a few works. For example: — M. Mahoney, "Fast Text Compression with Neural Networks", — P. Watta et al. "Image Comp...

All the reasons mentioned below is a small argument. Know that the photo is badly compressed, because it has a few similar points. What if you have 100 pieces to glue them into 1 and compress. In the end, increase the likelihood of meeting a greater number of the same points. What do you say?

Hello. Trying to write a working Huffman algorithm, but receive an incorrect result when decoding the compressed text. The last few characters will almost always get wrong, although the rest of the sequence is correct. For two days I can not understand what is the error, step-by-step debug doesn't help either. Example: Te...

There is a picture 1905х1253 completely blurred. The original picture that I downloaded weighed 178кб JPG, the preview in any program perfectly displayed, but if it is edited in PS, in the photo there are many different squares as the terrible image quality. I peresechenii this picture using Paint and got 252 KB JPG Have p...

To mind, for example, come in a breadth-first search in a larger graph, encryption-decryption with AES/compression-opening using LZW 4 GB of data in memory, calculate the sum of the squares of numbers from 1 to 100000. Help add to the list.

Is it possible to theoretically estimate the maximum possible compression of information? Of course, without losses and with the possibility of restoration (decompression).

Hi. What is the website from the show silicon valley, where the camera is installed in the gorge and takes the slot. I would also like to ask, maybe someone knows. Long, long ago watched a video theory house, but this video weighed 17кб, it is in good quality, sound, video, everything is fine. But the video and sound writte...

But actually I want to ask you Subs tovarischi. p.s. actually rather more interested in "Squeezes some gzip + unboxing on the device".

Hello! There is 2.5 hours one video to mov format, edited using final cut hd format. (720p) After render the video weighs in at 84 GB.. can not understand how to maximally compress the video? I have a Mac, so program from Windows please do not offer..

Prestashop CMS on php, Smarty template engine. For Smarty has a plug-in smarty_outputfilter_trimwhitespace, it compresses the HTML, but not Javascript. I would like to do the same for JS, but the decision "in a forehead" is not found. Advise?
