1. Photo Analysis Using Images to Extract Information

2. What is Digital Image Analysis? In Photo Analysis you edit and manipulate a image to extract information from it. In Photo Analysis you edit and manipulate a image to extract information from it.REMEMBER: Start with an image—end with an answer

3. What is Image J?  Image J is a computer program in which you can edit and extract information from digital photos.

4. How to Use Image J  Step 1: Determine what you want to measure. (length of a road, area of a building etc.)

6. How to Use Image J  Step 1: Determine what you want to measure. (length of a road, area of a building etc.)

7. How to Use Image J  Step 1: Determine what you want to measure. (length of a road, area of a building etc.)  Step 2: Find a reference in the picture (ex. A football field is 300 ft. in length, a standard parking space is 8 ft. wide etc.)

10. How to Use Image J  Step 1: Determine what you want to measure. (length of a road, area of a building etc.)  Step 2: Find a reference in the picture (ex. A football field is 300 ft. in length, a standard parking space is 8 ft. wide etc.)  Step 3: Find the relationship between the distances  Step 4: Get your answer

11. Applications of Photo Analysis  Measuring distances  Determining area  Urban planning (where to put roads, sewage, and drains)  Astronomy  Medical Applications  Photo Analysis can be used in many areas to determine certain information by only looking at a picture. In a sense a picture really is worth a thousand words.
