How Long Does Robaxin Stay In Ur System



Well, a few days ago I decided to make this great picture of Maximo Ruiz a little experiment with wavelets from the raw data.


Unlike proposed by Maxi making basic processing in PixInsight , which shows the decomposition of the image in layers, I have applied over the entire image processing wavelet, but through a mask. This mask is a combination of luminance and a star mask using the following expression in PixelMath:

mask * ~ star_mask

All wavelets settings I have taken completely out of line, before any transfer function halftones. Previously I have neutralized the background using the Background JavaScript Neutralization script written by Oriol Lehmkuhl , which is publicly available at: http://pixinsight.com/forum/viewtopic.php?t=799

Here you can see results obtained in a mouse-over comparison . Please place your mouse cursor on the links below and wait until upload pictures:

The first wavelet transformation is basically a technique of image restoration, in which I highlighted the small details scale and increased the overall contrast across the galaxy, using only all the luminance parameters.

The second transformation is designed to enhance the image chroma. By increasing the brightness and contrast of small structures of the luminance is almost always a loss of color saturation. In http://pixinsight.com/examples/deconvolution/Gemini-NGC5189/en.html Juan Conejero proposed for enhancement of color saturation more elegant color adjustment using curves. This procedure is a hyperbolic transfer function. And this is precisely what I have done here. This function is usually applied on large-scale components without affecting small, only on those structures represented in the residual layer of wavelet transformation. And of course in a completely linear.

These are the icons of the process used in this example:


To load icons on the platform process Core 1.2 PixInsight do click with right mouse button on the merits of the application and select Load Process Icons ... Finally you have to double click on the icon PixInsight Core process and automatically load the settings in the window ATrousWaveletTransform .

So this is my small contribution.
