Can someone advise me what the most sensible way is to read jpeg images? For our work with image analysis and eye-tracking we have been using the rimage package, on both Macs and Windows PCs. But while setting up a new Windows machine yesterday, I see that rimage is regarded as orphaned, and no Windows binary is available. I eventually found an old zip file for the package, so I

When an RGB photo is displayed using R's image() function with the help of the pixmap (or rimage) package it is common to see an anomalous white line running across the picture (either horizontally or vertically). The line can be removed by simply stretching the image frame a little in the direction perpendicular to the anomalous line, or by maximizing the image frame (tested under Fedora 10;

The question is how to use a URL in place of a file= argument for read.*.functions that do not support this internally. e.g., utils::read.table() and her family all support a file= argument that can take a URL equally well as a local file. So, if I have a file on the web, I can equally well do > langren <- read.csv("langrens.csv", header=TRUE) > langren <-

Dear all, Several days ago, I posted How to write a bmp file pixel by pixel. Instead of bmp, I succeeded in writing a PPM file by using the pixmap package. Thanks for the hint generously provided by Uwe Ligges. Now I have a new question. How to convert a PPM file to BMP file in R? I know I can do this in photoshop or by some other softwares, but I think if I Can do this in R, that

Dear R list members I would be grateful if anyone could guide me to a solution for fixing my rimage package problem described below. I recently upgraded my machine from fedora core 3 to fedora core 6 and then upgraded R from version 2.3.1 from version 2.4.1. I then fired up R, tried to load the rimage library and received the following messages: > library(rimage) Error in dyn.load(x,

Hi, all. I searched a lot at mailing list, installed EBImage and gtk packages, but I couldn't make this simple work: How to add a image file (jpg or bmp ou gif) to an existing plot window (not plot over the image), like the code below (pseudo function add.image): plot(1:10,1:10,main="test") image = read.X("myimage.jpg") add.image(image, x.left=2, y.bottom=4,

Dear all I prepared some image processing routine which depended on package ReadImages. Basically I imported image to R, changed rgb to grayscale, normalised an image made some selections and changed to image by imagematrix. Recently I learned that this package was removed from CRAN and can not be used in R 3.0.0. What options I have now to import image to R, change it to grayscale, make some

Buenas dias a tod@s, Quisiera saber si alguien tiene experiencia con el procesamiento de imágenes (en formatos JPEG o PNG) en R y la búsqueda de similitudes / diferencias entre ellas. La idea de lo que me gustaría hacer es: tomar una imagen, cargarla en R y luego analizar su estructura. Para las dos primeras tareas, la libreria ReadImages en CRAN me ha sido útil, pero para la segunda, hasta

Hi, We have recently been using the tiff package for reading tiff images into the Bioconductor Package EBImage. This has been extremely helpful in conjunction with other steps to eliminate dependencies on ImageMagick. However, it seems that 12-bit images are not supported. We were wondering if there are plans to extend the functionality of the readTIFF() function in the tiff package to

Is there any way to write an imagematrix generated by the rimage package? Reproducible example: library(rimage) x <- read.jpeg(system.file("data", "cat.jpg", package="rimage")) png("newcat.png") plot(x) dev.off() The newcat.png image is different from the original file, because there are ugly white borders around it.
