Python alloc Examples

Example #1

import cv2, cv
import numpy as np

#./pca_gen.py ./image_dir pc_size xblks yblks

	gist.process(im)
	gist.get(desc,0,320)

	if pcadata == None:
		pcadata = desc[0]
	else:
		pcadata = np.hstack([pcadata, desc[0]])
		
pcadata = np.transpose(pcadata)
print pcadata.shape
mean, eigenvectors = cv2.PCACompute(pcadata, maxComponents=int(sys.argv[2]))

print "Primary Component count ", eigenvectors.shape
