This is pretty funny because modern ECG machines generate digital output. You might first look into whether you can get the digits directly from the machine rather than scans of paper. But suppose you can't. I assume you asking how to find numerical coordinates for the curve by scanning and then

@Deepak: Digitization of the image doesn't have a algorithmic approach, (unless you need to compress it) But, i see that you are asking for a way to convert the image (jpg) into a memory representation. I am not sure of matlab, but, using java (images API) you have to read the data into

1 month back I wrote C++ code using Magick++ to zoom a image without distorting the Pixels . In that Code we can extact the Pixel attributes which are the Combination of Red , Blue and Green and Alpha attributes(Contributes to Picture Transparancy So , not present in Every Image ). But RBG
