Gray Level Co-occurrence Matrix (GLCM) Texture measures using Sentinel-1 in SNAP

A co-occurrence matrix or co-occurrence distribution (also referred to as gray-level co-occurrence matrices GLCMs) is a matrix that is defined over an image to be the distribution of co-occurring pixel values (grayscale values, or colors) at a given offset. Whether considering the intensity or grayscale values of the image or various dimensions of color, the co-occurrence matrix can measure the texture of the image. Because co-occurrence matrices are typically large and sparse, various metrics of the matrix are often taken to get a more useful set of features.
in this video, we've shown you sentinel-1 image pre-processing and applying GLCM to your images. all the processing has been applied in SNAP software which is a powerful software for Sentinel images processing.
if you had any question about the video, ask in the comments.

Thanks for this tutorial

[@rsgis6997]

You're welcome 😊

[@shahinjafari7870]

Very good

[@rsgis6997]

Thanks

[@jigarsolanki5232]

I think speckle filtering should not include in the processing steps of GLCM..

[@rsgis6997]

What is your reason?

[@bestiranianmusicschannel2542]

Very nice tutorial

[@rsgis6997]

Many many thanks

[@shahinjafari7870]

👍👍👍

[@rsgis6997]

Thank you

[@ayushik4600]

Very nice video sir. How can we use these texture bands in ArcGIS for parameter extraction

[@rsgis6997]

you're welcome
To extract texture from images in ArcGIS, you can write the formula of any type of texture and apply it to the image

[@ulfahdurrotulhikmah2966]

is it possible to measure glcm texture using sentinel 2?

[@rsgis6997]

Hello
The exact same texture cannot be extracted
Textures related to Sentinel 2 images can be extracted

[@RonaldoAlmeida-g9u]

Can I aplly GLCM in spectral images?

[@rsgis6997]

Yes you can

[@majilybalo5100]

Good day, sir. May I inquire about the possibility that GCLM may be used as a predictor in soil moisture estimation utilizing the random forest algorithm?

[@rsgis6997]

Yes we can

[@majilybalo5100]

@@rsgis6997 Hello again, sir. I'd want to know how to get the vh and vv backscattering data to a certain place on the map, please, sir. I appreciate your response in advance.

[@pangpangzhu]

Good day sir,if I have two I images that need to be GLCM, do I need to stitch them together first or to do them separately and then stitch them together? If stitching is possible, is it after the Convert bands to db operation?

[@rsgis6997]

Hello
Good time
It is better for you to do the mosaic operation first
Next, let's apply the GLCM operation
Yes
