This book was released on 2018 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: As semantic segmentation provides the class and the location of objects in a captured scene, it has been one of the core algorithms in many computer vision applications including autonomous driving, robot navigation, surveillance camera system, and human-machine interaction. Most of these applications demand high accuracy, robustness, and efficiency to understand a captured scene accurately in a timely manner in order to avoid accidents, to provide a meaningful warning, and to communicate naturally. We address this needs by using two popular approaches: random forest and deep neural network. We start by introducing a cascaded random forest for binary class segmentation. The framework first detects regions of interest and then segments foreground in the regions. Since the detection reduces the regions for the segmentation forest, the cascaded scheme improves efficiency and accuracy. We then explore learning more robust representations in a random forest. Since predetermined constraints in typical feature extractors restrict learning and extracting optimal features, we present a random forest framework that learns the weights, shapes, and sparsities of feature extractors. We propose an unconstrained filter, an iterative optimization algorithm for learning, a processing pipeline for inference. Experimental results demonstrate that the proposed method achieves real-time semantic segmentation using limited computational and memory resources. Moreover, we present a method to learn/extract depth-adaptive features in a deep neural network. It accomplishes a step toward depth-invariant feature learning and extracting. Since typical neural networks receive inputs from predetermined locations regardless of the distance from the camera, it is challenging to generalize the features of objects at various distances. Hence, we propose the depth-adaptive multiscale convolution layer consisting of the adaptive perception neuron and the in-layer multiscale neuron. The adaptive neuron is to adjust the receptive field at each spatial location using the depth information. The multiscale neuron is to learn features at multiple scales. Experimental results show that the proposed method outperforms the state-of-the-art methods without any additional layers or pre/post-processing. Lastly, we present applications of segmentation including sign language fingerspelling recognition and hand articulation tracking. We also present a potential data augmentation method using generative adversarial networks.

Download or read book Image Processing and Forward Propagation Using Binary Representations and Robust Audio Analysis Using Deep Learning written by Fabrizio Pedersoli and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis consists of three main topics: document segmentation and classification into text and score, efficient computation with binary representations, and deep learning architectures for polyphonic music transcription and classification. In the case of musical documents, an important problem is separating text from musical score by detecting the corresponding boundary boxes. A new algorithm is proposed for pixel-wise classification of digital documents in musical score and text. It is based on a bag-of-visual-words approach and random forest classification. A robust technique for identifying bounding boxes of text and music score from the pixel-wise classification is also proposed. For efficient processing of learned models, we turn our attention to binary representations. When dealing with binary data, the use of bit-packing and bit-wise computation can reduce computational time and memory requirements considerably. Efficiency is a key factor when processing large scale datasets and in industrial applications. SPmat is an optimized framework for binary image processing. We propose a bit-packed representation for binary images that encodes both pixels and square neighborhoods, and design SPmat, an optimized framework for binary image processing, around it. Bit-packing and bit-wise computation can also be used for efficient forward propagation in deep neural networks. Quantified deep neural networks have recently been proposed with the goal of improving computational time performance and memory requirements while maintaining as much as possible classification performance. A particular type of quantized neural networks are binary neural networks in which the weights and activations are constrained to $-1$ and $+1$. In this thesis, we describe and evaluate Espresso, a novel optimized framework for fast inference of binary neural networks that takes advantage of bit-packing and bit-wise computations. Espresso is self contained, written in C/CUDA and provides optimized implementations of all the building blocks needed to perform forward propagation. Following the recent success, we further investigate Deep neural networks. They have achieved state-of-the-art results and outperformed traditional machine learning methods in many applications such as: computer vision, speech recognition, and machine translation. However, in the case of music information retrieval (MIR) and audio analysis, shallow neural networks are commonly used. The effectiveness of deep and very deep architectures for MIR and audio tasks has not been explored in detail. It is also not clear what is the best input representation for a particular task. We therefore investigate deep neural networks for the following audio analysis tasks: polyphonic music transcription, musical genre classification, and urban sound classification. We analyze the performance of common classification network architectures using different input representations, paying specific attention to residual networks. We also evaluate the robustness of these models in case of degraded audio using different combinations of training/testing data. Through experimental evaluation we show that residual networks provide consistent performance improvements when analyzing degraded audio across different representations and tasks. Finally, we present a convolutional architecture based on U-Net that can improve polyphonic music transcription performance of different baseline transcription networks.

Available in PDF, EPUB and Kindle. Book excerpt: Segmenting image into multiple meaningful regions is an essential task in Computer Vision. Deep Learning has been highly successful for segmentation, benefiting from the availability of the annotated datasets and deep neural network architectures. However, depth-based hand segmentation, an important application area of semantic segmentation, has yet to benefit from rich and large datasets. In addition, while deep methods provide robust solutions, they are often not efficient enough for low-powered devices. In this thesis, we focus on these two problems. To tackle the problem of lack of rich data, we propose an automatic method for generating high-quality annotations and introduce a large scale hand segmentation dataset. By exploiting the visual cues given by an RGBD sensor and a pair of colored gloves, we automatically generate dense annotations for two-hand segmentation. Our automatic annotation method lowers the cost/complexity of creating high-quality datasets and makes it easy to expand the dataset in the future. To reduce the computational requirement and allow real-time segmentation on low power devices, we propose a new representation and architecture for deep networks that predict segmentation maps based on Voronoi Diagrams. Voronoi Diagrams split space into discrete regions based on proximity to a set of points making them a powerful representation of regions, which we can then use to represent our segmentation outcomes. Specifically, we propose to estimate the location and class for these sets of points, which are then rasterized into an image. Notably, we use a differentiable definition of the Voronoi Diagram based on the softmax operator, enabling its use as a decoder layer in an end-to-end trainable network. As rasterization can take place at any given resolution, our method especially excels at rendering high-resolution segmentation maps, given a low-resolution image. We believe that our new HandSeg dataset will open new frontiers in Hand Segmentation research, and our cost-effective automatic annotation pipeline can benefit other relevant labeling tasks. Our newly proposed segmentation network enables high-quality segmentation representations that are not practically possible on low power devices using existing approaches.
