color thresholding

[Prakash_Mahar]

How can I get the perfect Binary Image to process a color image by color thresholding function.

Actually a problem of glair in the image arises, and due to this I am not able to get the good result.

Hi Prakash,

Could you clarify what you mean by the "perfect binary image"?

If glare is causing you problems, you may be interested in the Local Threshold function (IMAQ Local Threshold).  IMAQ Local Threshold can be found in
Vision and Motion >> Image Processing >> Processing

Local thresholding compares every pixel with its neighbors, as opposed to the whole image, so the effects of glare can be reduced.  You can find out more about Local Thresholding in the Vision Concepts Manual, which is located in
Start >> All Program >> National Instruments >> Vision >> Documentation >> NI Vision >> Concepts_Manual.pdf
