Configurable SAMPLE_SIZE / LOW_SIZE

[kachkaev]

👋 again @btd! I’m curious if these params could be made configurable:

sharp-phash/index.js

Line 5 in 623d7fb

const SAMPLE_SIZE = 32;

sharp-phash/index.js

Line 51 in 623d7fb

const LOW_SIZE = 8;

This is an open question: technically, they can come as a third param of phash function (after sharp options), but I’m not sure if there is any value in this. I am still experimenting with perceptual hashes, so am trying to understand if changing sample sizing can improve the result.

Thanks a lot for putting this library together!

Hi, this parameters mostly was copied from original implementation. I made it sure that results of this lib match to libphash. In theory parameters could improve hash, but it very depends on the images you are dealing. If it is random images, defaults should be ok.
