alright - thats what i thought... :/

thank you for your help.

or maybe i am totally wrong - what exactly does " myMat.setTo(0, otherMat < threshVal); " do?

so i now have:

Imgproc.threshold(otherMat, myMat, threshVal, 0, Imgproc.THRESH_TOZERO_INV);

where do i find that inverting-flag? or where do i put it in?

another question is that i ONLY want to set the value to 0 if the condition is fulfilled and leave the value alone when not - because that is, what the C-Code says , right?

i guess, that threshold does not work for me - all the threshold-types are checking for - src(x,y) > thresh - but i need - if (src(x,y) < thresh) then 0 otherwise dst(x,y).

or am i wrong?

Hi,

i am actually porting some code to Android, but i don't know, how i can translate this code :

myMat.setTo(0, otherMat < threshVal);

As i think, every value in the matrix - myMat is set to 0 when the value at the corresponding place in "otherMat" is lower than "threshVal" - right?

I would just use a for-loop to solve this, but i think there must be a better way - just as in the C-Code Version.

Also - how to translate this C-Code:

myMat = myMat / ( otherMat+1 );

Thank you for your help.

Hi, there are ways to control the camera settings with the Camera.Parameters object - but that is not possible for the camerabridgeviewbase. How does it work there? Or is there even a better way to work with the camera? Or ist Camera.Properties - the same?

Thank you guys.

oh man - yes, that's exactly the thing i was searching for - thank you very much - i will have a deeper look into the api :)

I have a slightly different problem than in this question.

I want to mirror the Image, before anything is done with it. Until now i just read the columns of the incoming image and write them backwards into another. That is very slow and does not seem to work out. Is there an other possibility to just mirror the image?

here is my code: ` //my new matrices Mat nRGB = new Mat(); Mat nGRAY = new Mat();

            //i copy the originals onto them
    nRGB = mRgba.clone();
    nGRAY = mGray.clone();


    int thewidth = mRgba.width();
    for (int i = 0; i < mRgba.width();i++){
        for (int j = 0; j < mRgba.height();j++){

            if (mRgba.get(thewidth-i, j) != null){
                                    //rearrange the columns
                nRGB.put(i, j, mRgba.get(thewidth-i, j));
                nGRAY.put(i, j, mGray.get(thewidth-i, j));
            }
        }   
    }
            //copy them back onto the original
    mRgba = nRGB.clone();
    mGray = nGRAY.clone();`

Okay - thank you - i will test it and report back again then.

I can't seem to find the reason why it appears in the logcat view. About 100Times per second. How can i turn that message off? I'm running an Iconia Tab A210 and developing in Eclipse. Please help. Thank you.
