The success and popularity of deep learning is on the rise, partially due to powerful frameworks such as TensorFlow PyTorch, which make it easier develop models. However, these libraries also come with steep curves, since programming in quite different from traditional imperative explicit loops conditionals. In this work, we present a tool called TF-Coder for by example TensorFlow. uses bottom-...

Problem statement: The bitrate scalability is an important functionality that is defined in the Moving Picture Expert Group (MPEG-4) requirements. Since the traffic in a communication network varies with time, the capability of varying the bitrate of a speech coder is needed. Approach: This study proposes an approach to vary the bitrate by using a bitrate scalable tool which is attached with th...

In video processing, energy efficient real time video compression and transmission finds numerous applications. In this paper entropy coding is performed for video compression based on three‐dimensional discrete wavelet transform. Currently the most popular video coding approach is an extension of H.264/SVC standard. It provides high compression efficiency due to motion compensation and inter‐l...

Existing standard speech coders can provide high quality speech communication. However, they tend to degrade the performance of automatic speech recognition (ASR) systems that use the reconstructed speech. The main cause of the degradation is in that the linear predictive coefficients (LPCs), which are typical spectral envelope parameters in speech coding, are optimized to speech quality rather...

Speech intelligibility is the very essence of communications. When high noise can degrade a speech signal to the threshold of intelligibility, for example in mobile and military applications, introducing further degradation by a speech coder could prove critical. This paper investigates concepts towards a new speech coder that draws upon the field of image processing in a new multimedia approac...

We have shown that wavelet-TCQ image coders can be conngured to support hierarchical and progressive modes analogous to those speciied by the JPEG standard. These modes can be supported with little or no loss in coding eeciency. We have shown that a relatively simple entropy coder combined with a sophisticated quantizer results in a image coder with PSNR performance similar to that achieved usi...

Today, the primary constrain in wireless communication system is limited bandwidth and power. Wireless systems involved in transmission of speech envisage that efficient and effective methods be developed (bandwidth usage & power) to transmit and receive the same while maintaining quality-of-speech, especially at the receiving end. Speech coding is a technique, since the era of digitization (di...
