Hai, I’m trying to open an offline image as an array. I have try several steps, but i receive an error message. Maybe the command line is wrong. Can anyone help me?
Hi diyanah,
Are you using the EBImage package? That should allow you to open images as an array. From the help:
“RGB images are coded in 8 bits per channel, 24 bits per pixel, stored in an R integer array.”
If not, can you tell us what you are using? The relevant portions of your code would also be helpful.
ok..actually this is what i need to do….first i was given an image, a .tif image. i need to open it and as an array and i need to read the coordinate for at least 3×3…..from there i need to produce an algorithm. I’m still blur in R programming….all i understand right now is how to open data for example like a table in R….that is all. I already have imagemagic an EBIMage….but i don’t understand on how to use it with R. Is there any way or hint or any tutorial that u think might help me..?? thank u in advance.
Hi,
Currently I’ve been working on my final year project (Offline Signature Verification System). I’m required to use R programming and I’ve found that EBImage going well with R in image processing. I’ve successfully install R and EBImage package (along with ImageMagick and GTK). The thing is, when I try the command that I get from the “Introduction to EBImage” manual, I receive error/warning message. I hope you may help me solving these problem.
I have already change the directory to where the image is placed, and I have confirmed it by calling a .txt file and it is a success, but when I try for the image, I received these:
> f =system.file(“Images”,”user186g1.tif”, pakage=”EBImage”)
> user186g1 = readImage (f)
Warning message:
In readImage(f) : requested image not found or could not be loadedI try calling the directory by the using the PATH (I’m not sure whether the command is correct):
> f =system.file(“D:\\FYP ~\\image”,”user186g1.tif”, pakage=”EBImage”)
> user186g1 = readImage(f)
Warning message:
In readImage(f) : requested image not found or could not be loaded
