math - Binary run length encoding - Stack Overflow
网页2011年9月30日 · I want to implement run-length encoding, as efficiently as possible. Can you help me with this? I've googled binary RLE, but have found nothing of use. What I've tried this far - running RLE on the binary string using decimal counts and "A" as a separator denoting a change between 0 and 1, then converting the result from base 11 to base 64.
Encode numpy array using uncompressed RLE for COCO dataset
网页2018年3月26日 · 20. 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 pycocotools library has functions to encode and decode into and from compressed RLE, but nothing for polygons and uncompressed RLE.

RLE compression in c - Stack Overflow
网页2013年1月7日 · 1. One thing I see right off the bat is that you're incrementing j twice in each iteration. Perhaps you meant str[j] == str[j+1] as the condition. But, even if you do that, in that nested loop you can still reach territory out of your array's bounds. You need to make sure that not only the above condition is true, but also that str[j] is still ...
