LabVIEW
example denoise image (walevet)
Solved!
Katerina,
I assume that you have access to the Vision VIs. The Wavelet Data Samples VI included as part of the Example has a variety of "built-in" data. Replace this VI (the first one called in the DeNoise VI) with a VI similar to the one shown below (this is a Snippet -- if you are using LabVIEW 2015, you should be able to drag this image to a blank Block Diagram and have it "magically" turn into LabVIEW code -- otherwise, it should be simple enough for you to code it yourself).
The File Dialog shown first prompts the user to choose an Image file (here restricted to *.jpg and *.png), initially starting in the Samples Pictures folder (on Windows 7). It then uses several IMAQ functions to create a buffer for the Image, read the Image File into the buffer, extract the pixels as a 2D array of U8, and dispose of the buffer. It returns the Image Pixels for you to experiment with the "De-Noise" operation.
I hope this is helpful.
