WebFrom Table 7 and Figure 6, one can see that ORB and SIFT shows the best matching rates. The results might slightly vary but SIFT and ORB provide the highest matching rates. The added salt and pepper noise is randomly distributed and hence may be affecting some of the key points, but both SIFT and ORB show almost equal performance. IV. CONCLUSION WebAdding any sort of concentrate to the exterior of a joint is known as “twaxing” it – and it’s an easy way to add potency to a run-of-the-mill joint. To twax a joint, simply lick the exterior and roll it in kief. For extra potency, coat the joint in honey oil before rolling it in the dry sift.

Webmore. The way the ratio test works is by evaluating the absolute value of the ratio when applied after a very large number of times (tending to infinity), regardless of the initial terms in the series. If the ratio near infinity is less than 1, then we know for certain that each term is becoming less and less and the series will converge. Web7.1. Limitations of the SIFT Ratio Test.
