Image processing

[pinochios]

The goal of using image processing is to eliminate all those insignificant data, because of the parameter we have. So that for every time the cubesat come in to the signal range, we can be able to get the important picture in one orbit.

More we will use the image processing software to eliminate the unnecessary pictures; such as picture that we only see a slice or half of the earth.

• DeepbeliefSDK

  • This is a framework implements the convolutional neural network architecture .The processing code has been highly optimized to run within the memory and processing constraints of modern mobile devices. It's also easy to use together with OpenCV. The SDK for Jetpac's iOS, Android, Linux, and OS X Deep Belief image recognition framework. github - https://github.com/jetpacapp/DeepBeliefSDK

• pastec

  • Pastec is an open source index and search engine for image recognition based on OpenCV. It can recognize flat objects such as covers, packaged goods or artworks. It has however not been designed to recognize faces, 3D objects, barcodes and QR codes.
