GEOMETRIC TRANSFORMATIONS - Image Appications of Interpolation

Author: Jennifer Mikenas

Grade Level: 9 - 12

Courses: Algebra II, Precalculus, Trigonometry, Calculus

Lesson Summary: The Geometric Transformations lesson introduces students to the image processing methods used by many photo-editing tools when transforming images. Students use knowledge of functions to interpolate, or approximate, data by hand.  Trigonometric ratios and sinusoidal functions are applied in Octave software to resize, rotate, and warp images.

IMAGE HIDING - A Geometric Exploration

Author:  Natasha Zapata

Grade Level:  9 - 12

Course:  Geometry

Lesson Summary:      Image Hiding (Steganography) is the process of taking one image and hiding it within another image.  This is used for security purposes to protect sensitive information and to send information without detection.  This lesson relates Geometry concepts including basic definitions, conditional statements, and geometric probability to the process of Image Hiding.
