Introducing Deepo

Given the current state of deep learning research and development, we may need to play around with different frameworks (e.g., PyTorch for research and fun, Caffe2 for edge device inference, etc). However, setting up all the deep learning frameworks to coexist and function correctly is tedious and time-consuming.

So I made Deepo, which contains a series of Docker images that

• allows you to quickly set up your deep learning research environment
• supports almost all commonly used deep learning frameworks
• supports GPU acceleration (CUDA and cuDNN included), also works in CPU-only mode
• works on Linux (CPU version/GPU version), Windows (CPU version) and OS X (CPU version)

and their Dockerfile generator that

• allows you to customize your own environment with Lego-like modules
• automatically resolves the dependencies for you

Real-time Bilateral Filtering

Many users have become accustomed to reducing wrinkles, freckles, and various blemishes from human subjects for a more visually appealing image or video. This can be achieved by applying an edge-preserving filtering called bilateral filter. However, a vanilla bilateral filter typically has a high computational cost necessitating a powerful CPU / GPU to process images in real-time. So I had been looking for an efficient alternative algorithm, and finally found

that can achieve a good trade-off.

I made a lightweight C++ library for this algorithm, and obtained the following results (RecursiveBF):

Get Lost in Moscow Metro

It is easy to get lost in Moscow Metro if you don’t know Russian and have never been to Moscow. But it’s fun as I’m gaining new experiences and challenging my boundaries in an unfamiliar land with unfamiliar people. BTW, Moscow subway stations are so beautiful and grandiose. It’s like visiting a museum.
