Hello all, <br><br>I am new to itk so please be patient with me. <br>I want to create a filter to convert a RGB image to a CIELUV colorspace image. In order to do that I need to multiply the RGB values with a matrix and the result with some other values.<br>
I realized the best way to do something like that is to copy an existing filter and just change the part I am interested in. I have trouble finding a suitable filter as a template. Could anyone give me a hint on how I can do this? Bear in mind that I'm still on the process of discovering how itk works.<br>
<br>Regards,<br>Nikolas Stathonikos<br>
