android - Using OpenCV, how to find the values of HSV channels of the "masked region" in a masked image? -

-

using opencv4android, how can hsv channels of first pixel of masked region in masked image (dilatedmat in following snippet)? i know we'd hsv channel values of first pixel hsvmat.get(0,0) don't know how apply masked region only, rather entire mat.

for example, following function camera frame passed argument, , have generated mask, how should proceed there?

note: please keep in mind masked region not rectangle, has irregular shape.

private void detectcoloredblob (mat rgbaframe) {          mat hsvimage = new mat();          imgproc.cvtcolor(rgbaframe, hsvimage, imgproc.color_rgb2hsv_full);          mat maskedimage = new mat();          scalar lowerthreshold = new scalar(85, 50, 20);          scalar upperthreshold = new scalar(135, 255, 77);          core.inrange(hsvimage, lowerthreshold, upperthreshold, maskedimage);          mat dilatedmat= new mat();          imgproc.dilate(maskedimage, dilatedmat, new mat() );           //****************what now???**************      }

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
