Would it be able to detect textual regions in an image as it depics kite/persons in the example image?

Yes, if you train those models using a dataset with box annotations. A more relevant model if you want to transcribe the text : https://github.com/tensorflow/models/tree/master/attention_o...

Earlier quoted context omitted.

Mobile focused version of tensorflow.

Lol. Parallel data computations across resource (including battery) constrained devices? Good news, the owner of the device is now the product. The device is also the product. Can't wait.

I'm going to guess that Google knows a thing or two about mobile devices and their performance characteristics. Also, feeding something through an already trained NN can be pretty darn performant. I'll wait and see what this ends up looking like, but I am hopeful.

Their repository is pretty neat! It includes three state-of-the-art architectures in object detection: Faster-RCNN, RFCN, and SSD. It is missing YOLO [1][2], though, which shares some similarities with SSD. Another detector is the recently released Mask-RCNN [3], which of course wouldn't be possible to be included in this publication as we can't travel through time yet.

There are already newer versions, Yolov2 and DSSD. See http://github.com/sbrugman/deep-learning-papers

In practice Faster R-CNN worked better for me than YOLOv2 as it, in contrast to what is reported in the paper, had a higher recall for the detect task I used it for.

"Speed/accuracy trade-offs for modern convolutional object detectors" seems to establish that Faster R-CNN beats R-FCN and SSD-type architectures in accuracy, however YOLOv2 can beat Faster R-CNN and R-FCN in speed, while retaining high accuracy.

What's the hype here. It's a curated model zoo, or?

The researchers have created a framework for object detection such that one can easily experiment with using different feature extraction networks, separated from the "meta-architecture" such as Faster R-CNN, R-FCN, or SSD, used to handle the object detection task. They compare many models using this framework, described in https://arxiv.org/abs/1611.10012 - and they were able to construct the winning entry of the COCO 2016 detection challenge based on this research.

Many SoCs have under-utilized DSPs that can be used for tensorflow.
