Hi All,

Does anyone give me a suggestion how to separate object and background for poor image? 1.bmp

Above image is from camera and image quality is not good. I want to measure the size of the object. Currently, I do these steps. 1.) Capture the image. 2.) Binaries the image. 3.) Dilate the image. 4.) Erode the image. 5.) Find blob.

But, I saw the size of the object is not so accurated. I don't know how should I improve the image quality before doing any process.

regards

U can use medianblur/Gaussianblur to reduce some noise and also u can use algorithms from photo module(this algorithms are slowly)

Hi, I had already used medianblur/Gaussianblur. It is not so helpful for that image. Which type of algorithms should I use from photo module?

What object you want to detect?

If you see "1.bmp" picture, you will see the object at center. That is the image which I want to find.
