How to pass an image from Python to Matlab?

I want to pass an image from my Python script to Matlab.

Following is my Python script:

import matlab.engine

from PIL import Image

import os

eng = matlab.engine.start_matlab()

image = Image.open('Tile_X0_Y14336.jpg')

image_mat = matlab.uint8(list(image.getdata()))

passimage = image_mat.reshape((image.size[0], image.size[1], 3))

eng.image_display(passimage)

This is my Matlab Script:

clc;

clear all;

close all;

function y= image_display(a)

a=imread(y)

figure;

imshow(a);

end

However, I am getting an error saying 'TypeError: None cannot be passed to MATLAB' in output window.

Can anyone please help me to pass an image from my python script to Matlab script?

Hi Rucha,

The "getdata" method produces a flat list of pixel values, which loses the original 2D structure of the image. Attempting to restore this structure using "reshape" can be problematic if the image is not in the expected format or if the reshaping does not match the original dimensions.

I tried the following code, and it worked for me. You might want to give it a try:

import matlab.engine
from PIL import Image
import numpy as np

eng = matlab.engine.start_matlab()
image = Image.open('image.jpg')
image_np = np.array(image)
image_mat = matlab.uint8(image_np.tolist())
eng.image_display(image_mat, nargout=0)

I hope it resolves your issue!!
