Homography Calculation

[Final Year Project] FPGA based Image Mosaicing using AI (log #7)

 

Homography

Homography gives the relation between the similar keypoints in the two images.

Feature Matching using Brute Force Matcher

Sift Descriptors

Each Keypoint extracted using the SIFT algorithm is represented using a 128-dimensional vector known as the descriptor vector.

What are Image Features?

Image features are a set of points in an image that can be distinctively identified even if the image undergoes certain modifications such as –

Temperature Control of Peltier Element #10

Finishing Touches, Applications and Possible Improvements

Finishing Touches :

To make the project presentable,tidy and to avoid the use of DC bench power supply we made use of a Switch Mode Power Supply unit (SMPS) that connects to AC Mains supply and provided us with 12 V DC.
