An agent on the ground reports that the enemy has hidden a supply of arms on a trail exactly 5400 meters from its beginning. You have an aerial photograph that shows the trail with all its twists and turns. You need to find the location of the arms cache on the map to guide an air strike.
Image_with_cursor would be used with an aerial photograph. The color options would be turned off. The module would include information about the scale of the photograph.
Students would be expected to discover the idea of approximating arc length with a polygonal path.
Describe the arc of the water squirting from the hose in the photograph below.
Image_with_cursor would be used with a photograph of water squirting from a garden hose. The color options would be turned off.
Students would be expected to collect data points and fit the data using quadratic regression.
Students could check their answer using another applet together with Javascript that would superimpose their curve on the photograph.
An agent on the ground took the telephoto photograph on the left below showing the leader of a band of terrorists. The color is poor because the photograph was taken with artificial light at night. The same agent made a photograph of the same scene during the day without the terrorist but with ordinary daylight. You have been tasked to enhance the photograph of the terrorist. Use linear regression to analyze how the colors were distorted by the artificial light. The use linear algebra to determine how to reverse the distortion. Finally, use the applet below to enhance the original photograph.
