Web(negative instances will not match the template). 2.2. RSTBC-invariant template matching To obtain RSTBC-invariant template matching, we said above that the query shape Q must be rotated by every angle and scaled by every factor. In practice, it is not possible to rotate and scale Q by every angle and scale, but only by some discrete set http://www.lps.usp.br/hae/PSIVT07_Hae_Sidnei_Grayscale_Template_Matching_Invariant_RSTBC.pdf
