I have an image stack of 500 images (jpeg) of 640x480. I intend to make 500 pixels (1st pixels of all images) as a list and then send that via COM1 to FPGA where I do my further processing.

I have a couple of questions here:

1. How do I import all the 500 images at a time into python and how do i store it?
2. How do I send the 500 pixel list via COM1 to FPGA?

I tried the following:

1. Converted the jpeg image to intensity values (each pixel is denoted by a number between 0 and 255) in MATLAB, saved the intensity values in a text file, read that file using readlines(). But it became too cumbersome to make the intensity value files for all the 500 images!
2. Used NumPy to put the read files in a matrix and then pick the first pixel of all images. But when I send it, its coming like: [56, 61, 78, ... ,71, 91].

Is there a way to eliminate the [ ] and , while sending the data serially?

Thanks in Advance! :)
