After mosaicking the hyspex image I want to do the Radiometric Calibration. But there is a problem.That is "calibration requires gain and offset for each band" message dialog box will appeared. So how can I solve this problem?
I already did EDIT ENVI HEADER, in that I clicked on add option, from there I selected data gain value and data offset value, and I have clicked OK. but the problem is that I don't have information about gain and offset in the metadata file, I don't know how to estimate them?
please need help

I am using jupyter-notebook to write some python code and generate figures. As I wanted to add tooltips on mouse hovering and other interactions with the generated graphs, I now use mpld3 to display the graph.
However, as I have quite a lot of things to plot, I need to increase the figure size. So, I putfig = plt.figure(figsize=(20, 10)).
When I display with the standard way, I can see all the figure in my notebook (with horizontal sliders if I increase a bit more the figsize).
But with the mpld3 display, the size of the zone where the figure is displayed seems to be fixed, and hence, I can only see the upper left part of my figure. There are no sliders or anything to increase the displaying zone size.
For example, this code generate a graphic, for which you will see only the upper left part:
fig = plt.figure(figsize=(20, 10))
plt.plot([3,1,4,1,5], 'ks-')
mpld3.display(fig)
Does anyone know how to deal with this ? That is, how to increase the default display zone size, in order to have bigger graphs ?
Thanks
Edit after comment:
Here is a screenshot of how it is displayed on my machine...
And I would like it to be displayed just as it is on yours !
So I guess the problem comes from elsewhere... do you have any idea of how to solve this ?
I hope I do understand your question correctly but in Ipython Notebooks you can only use excisting space and not flip the notebook into wide screen mode or alike. In my notebook the graphic is also displayed like you show.
However, there is an easy fix, simply reduce the figsize to for example (10, 5). The main idea with interactive plotting with mpld3 is that the user can zoom in to specific interesting details. For the presented example it would not make much sense but richer graphs are great to be explored interactively.
When I create a figure with MATLAB with a title, then use the File|Print option to print the figure, the title is clipped. Please try this code for an example
t = linspace(0,2*pi,1000);
s = sin(t);
figure
plot(t,s)
titleString = sprintf('Multi\nLine\nTitle');
title(titleString)
disp('Now press File|Print Preview on the figure and observe that the title is clipped.')
disp('This happens with all titles, the multi line title makes it more obvious.')
disp('I know I can fix it with Fill Page or Center, but I should not have too.')
You can also see the problem in print preview. As I say in the example code, I know I can get round the problem using Print Preview then Fill Page or Center, but I don't want people using my code to have to use a work around.
I have observed this problem with r2014a and r2015b. I assume other releasse are also affected.
Is there setting I can make before creating the figure that centres the plot or fills the page and makes the problem go away? Is there some other setting I should make to avoid the problem?
Here is a little more debug information. If I press File|Print Preview, MATLAB reports Left 0.64, Top -0.59, Width 20.32, Height 15.24. I guess the problem is related to the negative Top value. These are defaults from MATLAB; I have not made any attempt to change these values.
One extra thing. I am in the UK, so my default paper/printer setting will be for A4 paper, if that makes a difference.
Edit:
It looks like my problems are caused by two lines further up in my program:
set(0,'DefaultFigurePaperOrientation','landscape')
set(0,'DefaultFigurePaperType','A4')
I think that becuase plots expect to be on paper with a portrait orientation, I am seeing these problems.
Perhaps I should revise my question to: what to I need to change in MATLAB figures so they print correctly on landscape A4 paper (ideally in the center, scaled to fill the page, but with correct orientation). All this without using Print Preview.
But I am going to do this instead to code around my problem.
set(0,'DefaultFigurePaperOrientation','portrait')
set(0,'DefaultFigurePaperType','A4')
I can't seem to reproduce your problem on the computer I'm currently on (see the values I'm getting by default - Top is 8.11):
However, if your problem is what I think it is (I'm getting something that fits this description on another computer I'm working on), try adding _{ } at the end of your string. This is a TeX string meaning "subscripted space" which pushes the rest of the text slightly upward. You can also use ^{ } on the first line if the clipping is happening from the top. I found this workaround to work on axis titles and labels as well.
Exaggerated, the workaround looks like this:
titleString = sprintf('^{^{^{^{^{^{ }}}}}}Multi\nLine\nTitle');
Which shows the word "Multi" even for Top = -0.59.
If the above is not what you're looking for, you might want to look at the robust export_fig.
I can confirm that my clipping problems are caused by this line:
set(0,'DefaultFigurePaperOrientation','landscape')
I have revised my program to start with this instead.
set(0,'DefaultFigurePaperOrientation','portrait')
set(0,'DefaultFigurePaperType','A4')
And the problem has gone away.
Users can still print in landscape if they use the print preview feature.
I am running a simulink model in external simulation mode and am having the following problem: When I stop the simulation and get the data from the scope, it never saves more than the last 5,000 data points. I have tried unchecking "Limit data points to last:" checkbox, but that doesn't help. I also tried increasing that number to 10,000 but there was no difference in the number of points I was able to save.
I found that if I create a new model and set it to normal simulation mode, then I can save as many data points as I want. Can anyone explain why I might have this issue in external simulation but not normal simulation?
In external mode, data logging is effected by the Duration setting on the External Signal and Triggering panel of the External Mode Control Panel. Go to that panel and press the Help button for a description of Duration and how to change it
Is it possible to set maximal height of a picture in crystal report and preserve original ratio of a picture?
If can grow is disabled, every picture is streched or shrinked to default picture object size, if is enabled, I'm losing limits of picture size.
I'm using crystal reports for VS 2013 (13.0.5)
Actually I solved this problem for Visual Basic 5.0 and Crystal Reports 6.0 (Seagate version). You asked the newer version but maybe this gives you an idea to solve the problem or it may help some other guys searching an answer for their problems.
Before you assign the report source you can change the height of the picture:
Set crxFieldObject = Report.Sections.Item("D").ReportObjects.Item(269)
crxFieldObject.Height = theNewHeight
CRViewer1.ReportSource = Report
CRViewer1.ViewReport
PS: After you assign the report source you can not change the height property. Below code does NOT work:
Private Sub Section3_Format(ByVal pFormattingInfo As Object)
Picture1.Height = theNewHeight 'this code does NOT work
End Sub
In this code:
.Sections.Item("D")means the Detail Section of the report and
.Item(269) means the Picture Object. After you insert an OLE Object you can check the item number with a small code such as:
aa = Report.Sections.Item("D").ReportObjects.Count
For i = 1 To aa
Set crxFieldObject = Report.Sections.Item("D").ReportObjects.Item(i)
bb = crxFieldObject.Name
If Mid(bb, 1, 7) = "Picture" Then
crxFieldObject.suppress = False 'You can put a BreakPoint here to check the value of i
End If
Next i
Hope it helps
The answer is No. I did many tests and researches and I didn't found any way to control the height and, without controlling the height, it's not possible to fit an arbitrary image in the object box and keep is ratio at the same time.
Looks like it's and old problem.
But if all your images are limited to the same dimensions, like you have set your limits to 500x500, so you can have, for example, images that do 500x200, 500x500, 250x500, etc., there's a way to do it.
The object box needs to have the same ratio as your limits. In my example, 500x500, the ratio is 1:1 (square) so your object box needs to be square also. You need to check Can grow and, in the Image tab, set the size exactly like the object box's size. You also have to set the bitmap image size (right-click on the box, choose Bitmap Image Object then Modify) to the image limits (500x500).
Perhaps too late, but when you right click on picture -> shaping of the object
You've a checkbox "modular size", uncheck it and put manually the size you want on Image tab.
I'm a newbie to Matlab. I'm basically attempting to manually segment a set of images and then manually label those segments also. I looked into the imfreehand(), but I'm unable to do this using imfreehand().
Basically, I want to follow the following steps :
Manually segment various ROIs on the image (imfreehand only lets me draw one segment I think?)
Assign labels to all those segments
Save the segments and corresponding labels to be used further (not sure what format they would be stored in, I think imfreehand would give me the position and I could store that along with the labels?)
Hopefully use these labelled segments in the images to form a training dataset for a neural network.
If there is some other tool or software which would help me do this, then any pointers would be very much appreciated. (Also I am new to stackoverflow, so if there is any way I could improve on the question to make it clearer, please let me know!) Thanks!
Derek Hoiem, a computer vision research at the University of Illinois, wrote an object labelling tool which does pretty much exactly what you asked for. You can download it from his page:
