Table 2 A comparison of the STTORM-CD models. The mean cosine distance was computed using five embeddings from the history. The statistics are based on 10,000 measurements for a single 32\(\times\)32x10 tile. Throughput was calculated for input data in the form of 16-bit integers, which is commonly the format of raw satellite imagery. The results are presented in the format “minimum-maximum, \(\mu\): mean”. The measurements were conducted on an ARM Cortex A53, utilizing all four 1.5GHz cores on the Xiphos Q8 board.
