opencv - openv HSV is soo noisy -


good day

i try filter video subtracting colors in specified range. while recorded image still or not changed hsv filtered image looks shaken , not stable. shake or instability cause lot's of problem in processing. there way can filter image in stable way

this sample code of filter ... part of code

while (1)     {         //first frame read         cap.read(origonal1);         morphops(origonal1);         cvtcolor(origonal1, hsv1, color_bgr2hsv);          inrange(hsv1, scalar(0, 129,173), scalar(26,212, 255), thresholdimage1);            waitkey(36);          //second image read , convert hsv         cap.read(origonal2);         morphops(origonal2);         cvtcolor(origonal2, hsv2, color_bgr2hsv);          inrange(hsv2, scalar(28, 89, 87), scalar(93, 255, 255),thresholdimage2);          morphops(thresholdimage1);         morphops(thresholdimage2); //create mask detect motion of color range , don't  //care other colors motion detection         maskimage = thresholdimage1 | thresholdimage2;          //make difference between images          absdiff(thresholdimage1,thresholdimage2,imagedifference);          imagedifference = imagedifference&maskimage;         morphops(imagedifference);         imshow("threshold image", imagedifference);         //search movement update origonal image         searchformovement(thresholdimage1, origonal1);         imshow("origonal", origonal1);         imshow("hsv", hsv1);         imshow("threshold1", thresholdimage1);         imshow("threshold2", thresholdimage2);         //wait while give break processor         //waitkey(1000);       }

enter image description here enter image description here this sample of first input image .. let's want filter orange paper this example of second input in advance.

try function

fastnlmeansdenoisingcolored( frame, frame_result, 3, 3, 7, 21 );

it's slow trying.
