imagefluency package is not working

[bssengul]

Hello everyone,

I downloaded imagefluency package to analyze my images in Rstudio. I wrote code, added images to example-images file. But code is not working. I dont even get any error message from code. Can you help me about this situation?

library(imagefluency)

# Get complexity, contrast, simplicity and self similarity values of multiple images in a given folder (all images should be loaded in the "example_images" folder)

 imglist <- list("high_1.jpg", "high_2.jpg.jpg", "high_3.jpg", "high_4.jpg.jpg", "high_5.jpg.jpg", "high_6.jpg.jpg")


for (i in imglist) {

	i <- img_read(system.file("example_images", i, package = "imagefluency"))

	print(data.frame(img_complexity(i),img_contrast(i), mean(rgb2gray(i)), img_self_similarity(i)))

Best regards,
Beril

You need to contact the maintainers of the package about issues with the package. See the BugReports URL at CRAN - Package imagefluency

what steps did you take to place an image high_1.jpg in to the imagefluency's example_images folder ?
you probably shouldnt do this; as the example_images are what they are , and your own images shouldnt be a confusion around that. have your own folder, and make your code read the images from that.

I changed "example_images" as my document "high_resized" but still nothing changed.

[nirgrahamuk]

You are not understanding something.
the example_images provides in imagefluency are berries.jpg etc.

list.files(system.file("example_images",package = "imagefluency"))
 [1] "berries.jpg"      "bike.jpg"         "bridge.jpg"       "fireworks.jpg"   
 [5] "office.jpg"       "rails.jpg"        "romanesco.jpg"    "sky.jpg"         
 [9] "trees.jpg"        "valley_green.jpg" "valley_white.jpg"

why would you think that your own image 'high_resized' would be in the imagefluency example_images folder ? it wouldnt ...

do you know where your images are ?

[bssengul]

Because, In my first trial, I added my images to example_images file.

In my second trial, I completely changed "example_images" name and wrote "high_resized". than thought that it will reach high resized document and find images.

I dont know if you need additional help or not.
Have you verified the location of your files of interest ?
once you have a known location, you would not use system.file()
you can list.files() on where you think your location is to verify what files are there.
you can do an img_read on them like

img_read(file.path(my_location,imglist[[1]]))

assuming that my_location is set to the actual path where your images are

my_location <- "yourpathgoeshere"

you can use your for loop, but first you need to establish where your images are (avoid using system.file)

[stm]

Besides the issues with the folder already raised by nirgrahamuk, the code in your original post is missing a closing bracket for the loop.

Have you tried the proposed solution to your issue on github?

Assuming your images are in the folder high_resized, what does dir.exists("high_resized/") say? What is the result of file.exists("high_resized/high_1.jpg")?
If any of these commands are FALSE, then R cannot find your images (probably because you have to change your working directory first).

Best, Stefan (maintainer of imagefluency)

@stm

file.exists("high_resized/high_1.jpg")

Hello again, I am grateful for your answers! The code you adviced worked well for me this time and I handled my problem. Thank you so much everyone.
