The ICDAR 2021 Time-Quality Binarization Competition assessed the performance of 12 new and 49 other previously published binarization algorithms for scanned document images. Four test sets “real-world” documents with different features were used. For each set, top twenty in quality resulting two-tone images had their average processing time presented, yielding an account complexity.

Aims. The treatment of astronomical image time series has won increasing attention in recent years. Indeed, numerous surveys following up on transient objects are progress or under construction, such as the Vera C. Rubin Observatory Legacy Survey for Space and Time (LSST), which is poised to produce huge amounts these series. associated scientific topics extensive, ranging from study our galaxy...
