There are two color matching functions, 1931 and 1964. For the purpose of visualization on the computer, 1931 suffices. But for Car industries and others that need a larger viewing angles, 1964 is best.
@@georgiylevchuk8254 I see! I’m away now and don’t have access to the image that I used. I’ll be back in a few days and upload an ENVI image to the repository. I’ll let you know in a few days.
Do you have code for calculating the signal-to-noise ratio of hyperspectral imagery? if yes then please provide the link for the same or if you can explain the procedure for calculating SNR would also be helpful. I really appreciate any help you can provide.
@@Morteza_Sc Sir is it possible that I can use code without using ENVI as I have the dataset in the format of L1R, L1GST, and L1T only and I am unable to convert it into .hdr ? Or you could provide a dataset for the code that you have provided Or if possible can you tell me how I can get .hdr file for input.
Great video again. Already subscribed. Need a video on showing the reflectance spectrum for a given point🙌🏻Keep up the good work
Thank you so much!
It is a very Informative video again.
Is that the only color matching function you used? Or there are more? If yes, why you chose that?

Great post! Do you have an example of ENVI HSI files to use with your code? Thanks
Thank you so much! This example uses ENVI images.
@@Morteza_Sc I meant - can you please post a link to example ENVI image? Repo didn't contain one, and I'm struggling to find example online. Thanks

@@georgiylevchuk8254 The data is now included:
github.com/mortezmaali/True_color_reproduction_from_ENVI_Hyperspectral_Image_Python.git
can we use the same code if the data is in xml format?
send me an email at morteza.maali.y2@gmail.com to send you a revised code to do that!!

@@surendrakumarsahu7920 hi, I’m sorry, I’m away now but I’ll get back to you as soon as I’m back!! I am on an emergency trip!!
@@Morteza_Sc Thank you so much for your response sir, whenever you are free please help me on this.

hlo i didnt get the data file for working this python is there any other solution for this
