I am using C++ within Visual Studio Community 2013. I use the pre-trained GoogLeNet model to extract the loss1-fc layer output to use as a feature vector for each image. So far so good.</p>\n\n<p>Recently i tried changing my software for use with video frames. So i changed the first layer from an ImageData layer to a Memory layer, so i can send to Caffe a vector of OpenCV mats instead of the naive approach of writing each frame to disk and sending a file list to caffe.</p>\n\n<p>Now, i noticed i won't get the same results for the same images! When using the ImageData layer, there's no such thing. </p>\n\n<p>I use CPU (no Cudnn, no GPU).</p>\n\n<p>The function i use for feature extraction is the following:</p>\n\n<pre><code>void feature_extraction_pipeline_memory(boost::shared_ptr<Net<Dtype>> feature_extraction_net, vector<cv::Mat> imgs, vector<int> labels, float** blobFeats, vector<string> blob_names){\n\n boost::dynamic_pointer_cast<caffe::MemoryDataLayer<float>>(feature_extraction_net->layers()[0])->AddMatVector(imgs, labels);\n\n size_t num_mini_batches = imgs.size();\n size_t num_features = blob_names.size();\n int dim_features;\n int batch_size;\n vector<Blob<float>*> input_vec;\n vector<int> image_indices(num_features, 0);\n\n for (size_t batch_index = 0; batch_index < num_mini_batches; ++batch_index) {\n feature_extraction_net->Forward(input_vec);\n for (size_t i = 0; i < num_features; ++i) {\n const boost::shared_ptr<Blob<Dtype>> feature_blob = feature_extraction_net->blob_by_name(blob_names[i]);\n batch_size = feature_blob->num();\n dim_features = feature_blob->count() / batch_size;\n const Dtype* feature_blob_data;\n for (size_t n = 0; n < batch_size; ++n) {\n feature_blob_data = feature_blob->cpu_data() + feature_blob->offset(n);\n for (size_t d = 0; d < dim_features; ++d)\n blobFeats[i][(image_indices[i] * dim_features) + d] = feature_blob_data[d];\n\n ++image_indices[i];\n } // n < batch_size\n } // i < num_features\n } // batch_index < num_mini_batches\n}\n</code></pre>\n\n<p>The <code>imgs</code> vector is a vector of mat. The <code>labels</code> is a vector of int, all set to 0. I wrote all images to disk again once they were added to vector. I checked and there is no problem with that. So there is nothing wrong when loading the images.
