quantization steps. We can observe that the proposed compression only causes up to
1.8% recall loss at point B1 as compared with point B. But the query size is reduced
more than 90%. The curve of CHoG in the research by Chandrasekhar et al. [255]
is drawn in Figure 11.12, too. We can observe that they have similar recall at similar
query sizes. Both of them have a largely decreasing slope on recall when query sizes
become too small. One thing that we have to mention here is, that for the proposed
compression, the
