The IoU of a predicted set of object pixels and a set of true object pixels is calculated as:\n\n𝐼𝑜𝑈(𝐴,𝐵)=(𝐴∩𝐵)/(𝐴∪𝐵).\n\n# Submission File\nIn order to reduce the submission file size, our metric uses run-length encoding on the pixel values. Instead of submitting an exhaustive list of indices for your segmentation, you will submit pairs of values that contain a start position and a run length. E.g. '1 3' implies starting at pixel 1 and running a total of 3 pixels (1,2,3).\n\nThe competition format requires a space delimited list of pairs. For example, '1 3 10 5' implies pixels 1,2,3,10,11,12,13,14 are to be included in the mask. The pixels are one-indexed and numbered from top to bottom, then left to right: 1 is pixel (1,1), 2 is pixel (2,1), etc.\n\nThe metric checks that the pairs are sorted, positive, and the decoded pixel values are not duplicated. It also checks that no two predicted masks for the same image are overlapping.\n\nThe file should contain a header and have the following format. Each row in your submission represents a single predicted bird segmentation for the given ```<ImageId>```.\n\n```\nImageId,EncodedPixels  \n0114f484a16c152baa2d82fdd43740880a762c93f436c8988ac461c5c9dbe7d5,1 1  \n0999dab07b11bc85fb8464fc36c947fbd8b5d6ec49817361cb780659ca805eac,1 1  \n0999dab07b11bc85fb8464fc36c947fbd8b5d6ec49817361cb780659ca805eac,2 3 8 9\n```",
