object detection

[Madhubalan]

Hi,

   In the attached vi file,

In File Path,i am giving an input color image(Full room image which consist of printer,table,desktop computer)

In File Path2, i am giving an input color image(only the target object image,i.e the printer image)

In this i am using Local Binary Pattern(LBP) to get the LBP image of both the input image and also their histogram graph.By combining both the histogram graph(h(x),h(x)2),we can get a histogram score by using histogram intersection formula.

My aim is to detect the target object(printer) in the full room image(final output) by compaing both the both LBP image of the full room and the LBP image of the target object.

Thank you

Hi Madhubalan,

this is Vanessa. I had a look into your project. I really like to support you with your request. Please answer my following questions.

Some informations about the aim of your project would be nice. Where did you find the technique of comparing two histograms in order to identify an object? What can you say from the coefficient x/y 3=0,111?

From my point of view a histogram offers statistic informations. It is not the best choice to compare two images. What about a pattern matching?

Kind Regards,

Vanessa

P.S.: Please find some significant names for your elements. Image in and Image in 2 and so on is not very meaningful.

Hi Vanessa,

                 My aim of the project is to detect the object,in my project i have to detect the printer.

I am using the technique from the attached pdf file.

coefficient x/y 3=0,111?

Those values give the coordinates of the 3x3 neighbourhood pixels relative (+x, +y) to the center pixel (x, y). I choose to assemble the bits from the neighbourhood by starting from the top-left corner (+x = -1, +y = 1) and advancing clockwise. You can, of course, use an arbitrary order but you need to stick to one in the LBP calculations.

Hi Madhubalan,

thanks for your fast response.

The provided pdf file is really interesting. I am sorry for not been familiar with this technique.

Do you need any support? From this point of view your vi runs fine. Or do you want to offer your VI for other users?

Kind Regards,

Vanessa

Hi,

   I would like to detect the object using the technique in pdf by using histogram itersection

Thank you

Hi Madhubalan,

sorry for asking again: How can I support you? At which point do you get stuck?

Kind Regards,

Hi Vanessa,

                 As per the pdf after comparing both the images,i am getting a histogram score using histogram intersection formula,but i could not able to find an idea about how to detect the target image in the full room image using the histogram score.

Thank you
