# Comparison of realsense

Intel has rolled out a bounch of the realsense cameras for 3D sensing. However, those cameras are quite different besides their appearances and metrics, but also their technique.

# Letter perception emerges from unsupervised deep learning and recycling of natural image features

There is a recent paper on Nature on unsupervised deep learning of recognizing letter images.

# Accessing Crunchbase Dataset

Crunchbase has provdes datasets/api for user to utilize the database in Crunchbase. The data are provided in the following four ways. Assume \$user_key is the the user key you obtained from Crunchbase.

# palm read via neural network

There is a Taiwan scholar invented Handbot — the first palm reading chatbot using deep learning (CNN) to analyze one’s palm to predict his/her character traits, health, career, relationship and many more aspects.

# EventBus in Android lessons learned

Event bus can be very helpful when you need to pass events cross multiple objects back and forth. In such cases, the listeners may get messy.

There is a recent work published in CVPR, which utilizes neural network to help you convert 2D images to 3D objects. It starts by learning how we project 3D objects to 2D images and based on that, we revert the process to recover the 3D objects from 2D images.
