Shifting inferencing to a different worker thread, this would stop GUI from freezing, but still, buttons like stop won't work until inferencing has returned.

Documentation support for pull #29

Possibly, because after inferencing, image Matrices are still stored in the Sample Object, leading to high memory usage.
MassInferencer has to be altered for the same.

I was trying to view spinello's depth images. And the output I am getting is something like this.

And it doesn't match with the video.
So is there some problem in conversion from grayscale to color mapping of depth ?
Or this is the desired output ?

This is a sample conversion from grayscale

After running Detector, it stores the detections in a Json format, which the evaluator fails to read.

Support for build on MacOS which uses Apple's LLVM Compiler. This would require some changes in CMake files, and build instructions for MacOS using brew as the packet manager.

To Convert Datasets, there is a need to convert Classes from one dataset to another, especially to solve issues, like existence of synonyms between datasets for the same class. This can be solved by two methods listed below:

1. Using a robust mapping technique which can map between synonyms, similar classes, like couch and sofa, or if one dataset contains a parent class and the other all the children, for instance one dataset contains furniture and another chair, sofa, table, etc.
   A suitable data structure has to be used to implement such a mapping.
   Still this has a drawback if the original dataset contain a class which the desired dataset doesn't, in that case some classes have to be discarded leading to losses.

2. Writer also outputs a class names file, containing all the classes which have been encountered, but again this will make the reading process dependent on the resulting names file, and isn't a universal solution i.e wouldn't be valid outside DetectionSuite.

So, a good solution would be to incorporate both of them, i.e let the user decide, which one to opt for.

The idea is to increase the features of the sample generation tool. At the moment you can only modify bounding boxed of detected object but you cannot include new detections.

I just realized that tensorflow inference speed can be drastically improved by passing session as a parameter instead of graph to the inferencing function.
I will implement the same and submit a pull request

Documentation for pull #43 and #46
Done!!, Waiting for Pull to be evaluated!
See Docs here

So DetectionSuite, which is written in C++, may invoke inference of a neural network from TensorFlow-python for detection.

Maybe some pre-processing of the images can be required before injecting them into the TensorFlow network.

Maybe some post-processing of the network results (bounding boxes...) can be required to deliver them in the right structure to compute statistics.

Boost is very slow

Inferencers generally accept rgb images for inferencing whereas opencv reads images in BGR format, therefore it might be necessary for some cases to swap R and B channels.
So, an option has to be integrated in the UI to take care of this factor.
And by default it should be RGB.

Hi @chanfr ,
Actually, I wanted to discuss something about Caffe support. So, let me start with TensorFlow and Keras support first.
TensorFlow doesn't require anythink apart from the frozen_inference_graph.pb and is sufficient for generating inferences, for any network architecture, like SSD, Faster R-CNN, etc.
Whereas, Keras requires a config file and the weights for it, though, in newer versions only HDF5 file is enough which contains both.
But, it does require implementation of Custom functions like AnchorBoxesGenerator and L2Normalization which architectures like Faster R-CNN and SSD do require. And these functions have to be passed in the ModelBuilder.

Now, coming to Caffe, in order to implement support for networks like Faster R-CNN and SSD, people have made changes to the base repository, and reinstalled it support custom architectures like Faster R-CNN and SSD, because there is no support for them in the base repository, and these custom functions cannot be passed in the Model Builder.

So, we are left with 2 solutions to implementing Caffe support:

1. Fork the base repository's code and change it according to our needs, but this will increase a dependency and users would have to build Caffe again for caffe support.
2. OpenCV's dnn module has already implemented the same by writing all the custom layers required and custom fucntions in C++, and they have also written parsers for config file and .caffemodel weights file.
   And since OpenCV is already a dependency, we can use there module to implement caffe support.

Also, OpenCV doesn't have Keras support, and their TensorFlow support is too lengthy, and requires to generate a separate config file for the same.
So, we have better TensorFlow and Keras support, but we can use their Caffe implementation.

I am getting following error while linking DataSetEvaluationApp,

This possibly means that JdeRobotInterfaces isn't build using std=c++11, although it is supposed to.
Maybe, Ice isn't installed with c++11 standard.
I will try building ice from source and then try the same.

Is there any way to save the inference files that we get with deployer? I want to save the bounding boxes and the frames of the video. I really appreciate if you can help me know it.

[DeepLearningSuite] (http://jderobot.org/DetectionSuite)

There are some tools which do not support OpenCV3, in DetectionSuite, and these have to be updated

It typically took 20secs, and after #27 near 4.5secs according to @naxvm . But the same network model in ObjectDetector (python code) takes only 125ms. Maybe we should revisit this and find the cause of this delay (the C++ to/from Python conversion?)

Done !!!
See Viewer Doc here and Detector here

Hi @chanfr ,
I was going through the code written in DetectionsEvaluator.cpp here.
And, what if multiple objects of the same class are present. For example 4 chair(s) are present in a single sample. Then for a single detected chair, it will iterate over all the ground truth regions and the first one will be matched, which might not be the same object of the chair.

So, doesn't it assumes by default that detections are in the same order as Ground Truth Values.

Final make sentence missing at the DetectionSuite compilation instructions.

In order to add support for COCO dataset #5 , it is necessary to parse large json files of the order of 300MB for 2014 and 450 MB for 2017.
This would require a fast JSON parser.
boost property tree is vaer slow and takes up all of the ram (8GB) and then hangs.
So, there are 2 possibilities which are must faster and can be used.

1. rapidJSON: Parses in 14 seconds without taking much RAM.
2. nholmann::json: Parses in 38 seconds without taking much RAM.

Therefore, I have decided to use rapidJSON, and is a header only library can be added to our code in the Deps folder.

Link to Comparision Code

Also, I will be adding rapidJSON in the Deps folder, so that there is no need to add extra documentation to install it, and is compatible across all environments, and also to improve version compatibility.

as those generated from TensorFlow and Keras. Their code should be run from the C++ DetectionSuite code.

A Python based model should be trained on its corresponding neural networks middleware, but its inference step should be called from DetectionSuite, providing it an image as input and reading its output bounding boxes from DetectionSuite too.

instead of current cfg files. This way this tools follows the same (new) convention as all other JdeRobot nodes.

So DetectionSuite, which is written in C++, may invoke inference of a neural network from Keras-python for detection.

Maybe some pre-processing of the images can be required before injecting them into the Keras network.

Maybe some post-processing of the network results (bounding boxes...) can be required to deliver them in the right structure to compute statistics.

Current Default value is 0.5, this is mostly used for most inferencers

Write Inferences in the same reader dataset provided.
Currently, it is being saved n default json format.

OverWriteClasswithzero is enabled by default even if the Single Class Checkbox in converter is unchecked.
