Automated Lip Reading (ALR) is a software technology developed by speech recognition expert Frank Hubner. A video image of a person talking can be analysed by the software. The shapes made by the lips can be examined and then turned into sounds. The sounds are compared to a dictionary to create matches to the words being spoken.

The technology was used successfully to analyse silent home movie footage of Adolf Hitler taken by Eva Braun at their Bavarian retreat Berghof.

Automated CCTV lip reading is challenging due to low frames rates and smallimages, but the University of East Anglia is pushing the next stage of this technology Scientists at the.

General View

Audio-visual recognition (AVR) has been considered asa solution for speech recognition tasks when the audio iscorrupted, as well as a visual recognition method usedfor speaker verification in multi-speaker scenarios. The approach of AVR systems is to leverage the extractedinformation from one modality to improve the recognition ability ofthe other modality by complementing the missing information.

The Problem and the Approach

The essential problem is to find the correspondence between the audio and visual streams, which is the goalof this work. We proposed the utilization of a coupled 3D Convolutional Neural Network (CNN) architecture that can mapboth modalities into a representation space to evaluate the correspondence of audio-visual streams using the learnedmultimodal features.

How to leverage 3D Convolutional Neural Networks?

The proposed architecture will incorporate both spatial and temporal information jointly toeffectively find the correlation between temporal informationfor different modalities. By using a relatively small network architecture and muchsmaller dataset, our proposedmethod surpasses the performance of the existing similarmethods for audio-visual matching which use CNNs forfeature representation. We also demonstrate that effectivepair selection method can significantly increase the performance.

Code Implementation

The input pipeline must be provided by the user. The rest of the implementation consider the datasetwhich contains the utterance-based extracted features.

Under this system, once the design is completed by the design team, a number of construction companies or construction management companies may then be asked to make a bid for the work, either based directly on the design, or on the basis of drawings and a provided by a. The best modern trend in design is toward integration of previously separated specialties, especially among large firms. In the past, architects, interior designers, engineers, developers, construction managers, and general contractors were more likely to be entirely separate companies, even in the larger firms. Following evaluation of bids, the owner typically awards a contract to the most cost efficient bidder. Building construction process.

Lip Tracking

For lip tracking, the desired video must be fed as the input. At first, cd to thecorresponding directory:

The run the dedicated python file as below:

Running the aforementioned script extracts the lip motions by saving the moutharea of each frame and create the output video with a rectangular around themouth area for better visualization.

The required arguments are defined by the following python script whichhave been defined in the VisualizeLip.py file:

Some of the defined arguments have their default values and no further action isrequired by them.

Processing

In the visual section, the videos are post-processed to have an equal frame rate of 30 f/s. Then, face tracking and mouth area extraction are performed on the videos using thedlib library [dlib]. Finally, all mouth areas are resized to have the same size and concatenated to form the input featurecube. The dataset does not contain any audio files. The audio files are extracted fromvideos using FFmpeg framework [ffmpeg]. The processing pipeline is the below figure.

Input Pipeline for this work

The proposed architecture utilizes two non-identical ConvNets which uses a pair of speech and videostreams. The network input is a pair of features that represent lip movement andspeech features extracted from 0.3 second of a video clip. The main task is to determine if astream of audio corresponds with a lip motion clip within the desired stream duration. In the two next sub-sections,we are going to explain the inputs for speech and visual streams.

Speech Net

On the time axis, the temporal features are non-overlapping20ms windows which are used for the generation of spectrum featuresthat possess a local characteristic.The input speech feature map, which is represented as an image cube,corresponds to the spectrogramas well as the first and second order derivatives of theMFEC features. These three channels correspond to the image depth. Collectively from a 0.3 secondclip, 15 temporal feature sets (eachforms 40 MFEC features) can be derived which form aspeech feature cube. Each input feature map for a single audio stream has the dimensionality of 15 × 40 × 3.This representation is depicted in the following figure:

The speech features have been extracted using [SpeechPy] package.

Please refer tocode/speech_input/input_feature.pyfor having an idea about how the input pipeline works.

Visual Net

Lip Reading Lessons

Miroslav philharmonik ce keygen generator. The frame rate of each video clip used in this effort is 30 f/s.Consequently, 9 successive image frames form the 0.3 second visual stream.The input of the visual stream of the network is a cube of size 9x60x100,where 9 is the number of frames that represent the temporal information. Eachchannel is a 60x100 gray-scale image of mouth region.

Architecture

The architecture is a coupled 3D convolutional neural network in which twodifferent networks with different sets of weights must be trained.For the visual network, the lip motions spatial information alongside the temporal information areincorporated jointly and will be fused for exploiting the temporalcorrelation. For the audio network, the extracted energy features areconsidered as a spatial dimension, and the stacked audio frames form thetemporal dimension. In the proposed 3D CNN architecture, the convolutional operationsare performed on successive temporal frames for both audio-visual streams.
