You need LOTS of more information for reading and dealing with raw data, and its information YOU have, and we dont. Or maybe the las 4 bits are some kind of encoding! There are different ways of reading and storing RGB images!Īll this information is hardware specific, so there is no way we can help you, as we dont know your hardware. You'll need to scale them to 8 bits (or something else, but something matlab can handle )for saving and displaying.Įven more, sometimes raw data is not even stored linearly! (look here for tips of reading raw data) so you may be getting wrong images. Each row of map is a three-element RGB triplet that specifies the red, green, and blue components of a single color of the colormap. Say, your camera is a 14 bit per pixel camera, then you need to scale the binary numbers you get accordingly. Colormap associated with indexed image X, specified as a c-by-3 matrix with values in the range 0, 1. In each image type, pixels are stored in. J im2uint8( I ) converts the grayscale, RGB, or binary image I to uint8, rescaling or offsetting the data as necessary.

Then converted to 1D matrix using reshape command. The image size is also a constraint, so it needs to be fixed for conversion. Usually in raw you will have binary numbers, you need to convert them to your amplitude. Image Processing Toolbox supports binary, indexed, grayscale, and truecolor image types. For converting into text file, it needs to be converted into 1D matrix and then to text file using file write in matlab. ‘whos f’ gives name, size, bytes, class and attributes of the array ‘f.’. You can find additional information about the array using ‘whos’ command. It seems that you know the shape of your data, guessing by your ' reshape(a,768, 576, 3) ', but do you know its amplitude? To get the size of a 2D image, you can write the command: M,N size (f) This syntax returns the number of rows (M) and columns (N) in the image. tif format (,possibly product from remote sensing software,) to. Its probably writing an image and you are not seeing what you want, rigth? The problem with 'RAW' format is that it is not a format itself, its literally raw data from the camera. Vice versa, how can I convert the image in. This is not a perfect answer, but too long for a comment.
