i am trying to detect the suit and value of a playing card, OCR doesn't work for this problem, however i suspect i should use the image labeller app within matlab to label the ground truth data for each card. Any ideas of where to go from here?

I think using Deep Learning CNN clasification would be another option to consider if you have lots of different card face styles that you need it to work on.

yes,sir,may be use hu,lbp or other feature to classify,or just use cnn to train data

yes,sir,for example,we get lbp feature vector,such as
clc; clear all; close all;
im = rgb2gray(imread('football.jpg'));
v1 = extractLBPFeatures(im,'Upright',false);
im = imread('rice.png');
v2 = extractLBPFeatures(im,'Upright',false);
then use them to svm or bp to make classify model
if data not enough,may be use imageDataAugmenter to extend

You could use normalized cross correlation. See attached demo.
