Caffe has command line, Python, and MATLAB interfaces for day-to-day usage, interfacing with research code, and rapid prototyping. While Caffe is a C library at heart and it exposes a modular interface for development, not every occasion calls for custom compilation. Now, I am trying to install caffe with matlab interface. I am able to build it with a gcc-5 warning but I am unalbe to make test it. I am running into errors given below: My system config: Ubuntu -16.04, opencv 2.4.9, gcc-5, g-5, Matlab2017b.

In the previous post on Convolutional Neural Network (CNN), I have been using only Scilab code to build a simple CNN for MNIST data set for handwriting recognition. In this post, I am going to share how to load a Caffe model into Scilab and use it for objects recognition.
This example is going to use the Scilab Python Toolbox together with IPCV module to load the image, pre-process, and feed it into Caffe model to recognition. I will start from the point with the assumption that you already have the Python setup with caffe module working, and Scilab will call the caffe model from its’ environment. On top of that, I will just use the CPU only option for this demo.
Schwartz 1 7 – template based graphics code generator. Let’s see how it works in video first if you wanted to:
Let’s start to look into the codes. Ubar 3 1 2 – the dock replacement.
The codes above will import the python libraries and set the caffe to CPU mode.
This will load the caffe model, the labels, and also the means values for the training dataset which will be subtracted from each layers later on.
Initially the data would be reshape to 3*227*227 for the convenient to assign data from the new image. (This likely is the limitation of Scipython module in copying the data for numpy ndarray, or I’ve find out the proper way yet)
This part is doing the “transformer” job in Python. I personally feel that this part is easier to be understand by using Scilab. First, we read in the image and convert it to 227 by 227 RGB image. This is followed by subtracting means RGB value from the training set from the image RGB value resulting the data from -128 to 127. (A lot of sites mentioned that the range is 0-255, which I disagreed).
This is followed by transposing the image using permute command, and convert from RGB to BGR. (this is how the network sees the image).
In this 3 lines, we will reshape the input blob to 1 x 154587, assign input to it, and then reshape it to 1 x 3 x 227 x 227 so that we could run the network.
Finally, we compute the forward propagation and get the result and show it on the image with detected answer. Uninstall endnote x7 mac.
