                VideoFromImageStack


This class allows the user to treat a stack of grayscale images in a 3D numpy array as a video.
    We assume that the dimensions of the array are ordered as (frame number, width, height).

Instance Methods

[hide private]

__init__(self, imageStack, size=None)
imageStack is the numpy ndarray that represents the image stack.

source code

query(self)
Must be overridden to implement the specific frame-grabbing required by different video sources.

source code

__iter__(self)
Return an iterator for this video

init(self, imageStack, size=None)
(Constructor)

source code


    imageStack is the numpy ndarray that represents the image stack. Should be of dimensions (frames,width,height).
    Optionally, this can be any object, such as pyvision.ImageBuffer, that implements asStackBW() method that returns
    the grayscale image stack.
size is the optional width,height to resize the input frames.
