I found the issue. It is due to the resizing of the cam variable using skimage.transform.resize().
from skimage.transform import resize
capi=resize(cam,(128,128,128))
This resizing implementation results in cam[ : , : , 0 ] equalling cam[ : , : , 1 ] and cam[ : , : , -1 ] equalling cam[ : , : , -2] for me.
Swapping the resizing function which relies on scipy.ndimage.zoom()) worked for me.
Now each slice now is unique.
def resize_volume(img, desired_depth, desired_height, desired_width):
"""Resize across z-axis"""
# Get current depth
current_depth = img.shape[-1]
current_width = img.shape[0]
current_height = img.shape[1]
# Compute depth factor
depth = current_depth / desired_depth
width = current_width / desired_width
height = current_height / desired_height
depth_factor = 1 / depth
width_factor = 1 / width
height_factor = 1 / height
# Rotate
img = ndimage.rotate(img, 90, reshape=False)
# Resize across z-axis
img = ndimage.zoom(img, (width_factor, height_factor, depth_factor), order=1)
return img
capi = resize_volume(cam,128,128,128)

hello @JamesCallanan @fitushar please let me know how much memory is required for it? as I am getting OOM memory exhaustion error. I have 24GB GPUs and 128GB RAM
