+"""Utilities to perform various transforms.
+
+This module includes tools to transform images and volumetric data
+such as:
+
+- Geometric Transformations: These transforms change the shape or position
+of an image. They are useful for tasks such as image registration,
+alignment, and geometric correction.
+Examples: Affine transform,  Projective transform, Euclidean
+transform etc.
+
+- Image Resizing and Rescaling: These transforms change the size or
+resolution of an image. They are useful for tasks such as
+down-sampling an image to reduce its size or up-sampling an
+image to increase its resolution.
+Examples: Resize, Rescale etc.
+
+- Feature Detection and Extraction: These transforms identify and
+extract specific features or patterns in an image. They are useful
+for tasks s object detection, image segmentation, and
+feature matching
+Examples: Hough transforms, Pyramid Transforms, Radon transforms etc.
+
+- Image Transformation: These transforms change the appearance of an
+image without changing its content. They are useful for tasks such a
+creating image mosaics, applying artistic effects, and visualizing
+image data.
+Examples: Wrap transform, Inverse transforms etc.
+
+For more information on each transform, see their respective docstrings
