The scientific image viewer
What is it?
CImgExplorer is a viewer for scientific intensity images. It shows intensity images as false-colour images, displays the value below the cursor, and allows zooming and selections. The histogram is shown and the false-colour scale may be tweaked to best view the required features. Automatic histogram optimisation is possible, basic analysis filters like intensity conversion of multichannel images and Gaussian mean filter are available.
from the Sourceforge project page
- set histogram resolution (leads to new calculation of the histogram)
- median filter of the histogram (button on top right)
- fit Gaussian: fit a Gaussian into the histogram, with the start value for the centre at the highest peak of the histogram
- intensity scale adjustment: adjust intensity space (range of the false colour scale) to (1) n standard deviations around the centre of the fitted Gaussian or (2) to the range beginning from the centre expanding to both sides until the histogram count drops below the fraction f of the peak value of the fitted Gaussian
- adjust the axes of the histogram display (double click on the axes to open the axis range dialog, or adjust the "Count max" spinbox for the pixel count axis)
- select sub-regions of the image
- draw line profiles, also with horizontal or vertical average
- show statistics of image or selections
- export false-colour image and corresponding colour scale (image will be bitmap image, e.g. PNG/TIFF, scale will be PDF)
- view different Bayer channels in separate views
- median filter
- Gaussian mean filter
- arithmetic (add to, subtract from or devide by another image, square root)
- Bayer pattern downsampling
- transform multichannel images to intensity images
Restrict selections to image area. Scroll when selection is made and the cursor is moved outside the view widget.
