Remove separated objects in an Image C# -

your appreciated. using c# , emgucv image processing

i have tried noise removal, nothing happens. tried image median filter, , works on first image, not work on second image. makes second image blurry , objects larger , more square-like.

i want remove distinct objects(green ones) in image below turn black because separated , not grouped unlike second image below.

image 1:

at same way, want in image below, remove objects -- (the black ones) -- not grouped/(lumped?) remains on image objects grouped/larger in scale?

image 2:

thank you

you may try gaussian blur , apply threshold image.

gaussian blur used effect in graphics software, typically reduce image noise , reduce detail, think matches requirements well.

for 1st image:

cvinvoke.gaussianblur(srcimg, destimg, new size(0, 0), 5);//you may need customize size , sigma depends on different input image.

you get:

then

cvinvoke.threshold(srcimg, destimg, 10, 255, emgu.cv.cvenum.thresholdtype.binary);

you get:

for 2nd image:

cvinvoke.gaussianblur(srcimg, destimg, new size(0, 0), 5);//you may need customize size , sigma depends on different input image.

you get:

then

cvinvoke.threshold(srcimg, destimg, 240, 255, emgu.cv.cvenum.thresholdtype.binary);

you get:

hope help!
