QUESTION

Why do I get different glcms when masking an image and when cropping it

Asked 2020-Jun-05 at 10:28

I'm trying to build an image classification model based on features extracted from GLCM. I want to mask some of the images to improve the model, and of course I don't want the GLCM to take those pixels in account. based on the following post I've implemented and conducted a test to make sure that GLCM works correctly for masked images:

1) Take an image and create a cropped version and a masked version(in the same pixels that were cropped).

2) converte images to int32 type and did the following:

Let's go through the code slowly. First we import the necessary modules, load an image of type np.int32 and increase the pixel intensities of all pixels of the image by 1:

skimage.feature.greycomatrix only producing diagonal values

Asked 2020-Jun-01 at 17:44

I am attempting to produce glcm on a trend-reduced digital elevation model. My current problem is that the output of skimage.feature.greycomatrix(image) only contains values in the diagonal entries of the matrix.

...

ANSWER

Answered 2020-Jun-01 at 17:44

If pixel intensities are correlated in an image, the co-occurrence of two similar levels is highly probable, and therefore the nonzero elements of the corresponding GLCM will concentrate around the main diagonal. In contrast, if pixel intensities are uncorrelated the nonzero elements of the GLCM will be spread all over the matrix. The following example makes this apparent:

I am trying to receive in Python the exact same results of the functions graycomatrix and graycoprops as in MATLAB. But the results differ and I am not able to write the code which will repeat the results from MATLAB.

I need GLCM features like contrast, correlation, energy and homogeneity.

Any advice is very appreciated.

ANSWER

Answered 2017-May-19 at 08:08

The GLCM features computed with Matlab and Python are different because the result of preprocessing the original image (namely conversion to grayscale, scaling and requantization) with your Matlab code differs from the result yielded by your Python code (i.e. array S). The following snippets make it apparent:

Displaying images using euclidean distance

I am doing a project using python and opencv(cv2). Here I am calculating the dataset's image's red, green and blue mean separately and also calculating the GLCM( contrast, energy, homogeneity, and correlation) and saving it in different list's. Now I have calculated the euclidean distance between query image with DB images, but I am unable to display the images with least distance. i have done the code partially, and it is like:

You can use numpy functions to get the euclidean distance between the DB images and query image in one go with minimum computations.

How to create a stack of an uploaded image in a shiny application

Asked 2019-Jun-13 at 15:08

I have the shiny app below which makes image recognition. I upload the image below and it is displayed as you will see. The issue is that I want to use the name of this file ("DJI_0104.jpg") inside the stack() function in order to create a stack of the image. Then I plot the result (textures). Basically I am looking for a way to use only the name of the uploaded image -like in R104() which works-. You can find the .jpg here

you can find more details here, but here is a solution: in the base64() reactive, inFile is built after the output of fileInput(), output which possesses 4 fields: name, size, type and datapath (see link above). As Stéphane Laurent underlined, using inFile$name shall make your shinyApp work.
