Images
selection
Open the Select images dialog box (View menu). This tool is a useful solution for select peculiar images in a set of images. For example, create a new sequence containing the best resolved images, after visual inspection.
First of all, enter the generic name of the input sequence. For example, if you want selected images in the sequence:
M51-1, M51-2, M51-3, M51-4, M51-5, M51-6
the generic name is M51-.
Then, enter the generic name of the output sequence, for example SM51 -, which will produce for example in the working directory the sequence:
SM51-1, SM51-2, SM52-3...
Now press then the button >>. The first image of the input sequence (M51-1 in the exemple) is diplayed. At this stage you can choose to copy this image in the output sequence by clicking the Save button, or skip to the following image by clicking on >> (you can retrogress if you click << button). After modification of the current image (threshold, dynamic stetchin,g, etc) you can reload in memory the original image by clicking the Reload button.You can also in the course of selection modify the current index number of the output images, which is practical to insert images in an old sequence.
If the View sequence option is selected, the input sequence which is displayed in the screen is that which is defined by the generic name Generic view, but the images saved are defined by the Generic name item. This possibility is for example very practical for sorting planetary images: the view sequence for example correspond to images treated by a unsharp masking in order to distinguish fines details, but the images actually saved in the output sequence are the unprocessed images for a future processing.
For example suppose the input sequence:
JUP1, JUP2, JUP3, JUP3, JUP4, JUP5, JUP6, JUP7, JUP8
Let us suppose a view sequence which takes again these same images, but with a specific processing:
TJUP1, TJUP2, TJUP3, TJUP3, TJUP4, TJUP5, TJUP6, TJUP7, TJUP8
If one selects images: TJUP1 TJUP5 TJUP7, we have the correspondance:
JUP1 -> SJUP1
JUP5 -> SJUP2
JUP7 -> SJUP3
