How to convert a figure in matrix of pixel?

11 views (last 30 days)
I have a picture and I want to convert this into a numeric matrix. I want to create a matrix of 1's and 0's where the 0's represent the orange pixels and the 1's represent the transparent pixels.
Can anybody help me?

@Rik and @Benjamin. The Mathematica code for this procedure is relatively simple, but I would like to get a version of the code in matlab.
image = Import[""]
data = ImageData[ChanVeseBinarize[image]]

filename = '';
img = imread(filename);
Name Size Bytes Class Attributes filename 1x79 158 char img 373x363x3 406197 uint8
bw = imbinarize( rgb2gray(img) );
whos bw
Name Size Bytes Class Attributes bw 373x363 135399 logical
Notice that the result is logical datatype, with 1 for the white pixels and 0 for the black pixels. Depending exactly what you are doing, you might need to convert that to double precision -- for example if you are wanting to use it as Alpha data, you will need to convert to double precision.

Depth cannot be calculated from a single 2d picture (unless there are cues such as color)
