COSIE.image_preprocessing.rescale_image

rescale_image(img, scale)[source]

Rescale an image by a given scale factor using skimage.transform.rescale.

Parameters

imgnp.ndarray: Input image array. Can be either a 2D grayscale image of shape (H, W), or a 3D color image of shape (H, W, C).
scalefloat: Rescaling factor. The same scale is applied to both height and width dimensions. If the input is 3D, the channel dimension is preserved.

Returns

imgnp.ndarray: The rescaled image array. The output values are kept in the original range of the input (preserve_range=True).
