- Encode numpy array using uncompressed RLE for COCO dataset
To create a COCO dataset of annotated images, you need to convert binary masks into either polygons or uncompressed run length encoding representations depending on the type of object The pycoco
- math - Binary run length encoding - Stack Overflow
Since you're coding bits, you probably want to use a bit-based RLE instead of a byte-based one In this context, you should consider Elias gamma coding (or some variant thereof) to efficiently encode your run lengths A reasonable first approximation for your encoding format might be: first bit = same as the first bit of the uncompressed string (to set initial polarity) remaining bits: Elias

- Use rle to group by runs when using dplyr - Stack Overflow
What is causing my rle -based grouping code to fail in dplyr, and is there any solution that enables me to keep using rle when grouping by run id? Update: As of 2023, this appears to have been fixed by the dplyr package, such that my original code works fine, and there's no need for any workarounds

- rle compression algorithm c - Stack Overflow
RLE can be done in one pass, there should not be a need to seek to the previous characters One way to solve this is to change the logic into looking at the previous characters and how many times they have been repeated, instead of trying to look ahead at future characters For instance: int repeatCount = 0; int previousChar = EOF;
- Find start and end positions indices of runs consecutive values
Because the start and end vectors are the same length as the values component of the rle object, solving the related problem of identifying endpoints for runs meeting some condition is straightforward: filter or subset the start and end vectors using the condition on the run values
- Encoding numbers in RLE Compression - Stack Overflow
I am working on implementing dynamic version of RLE compression On this version I only insert characters count in the RLE Code if it's more than 1, other than that I keep it as its original state
