Signal processing is a field of expertise applicable for a large variety of applications with high industrial impact and feasibility. This is why many patents in signal processing were initiated during the last few decades for large variety of data manipulation, image processing applications as well as for optimization of various devices and sub systems for communication. A large variety of applications that can benefit from the recent advances in signal processing capabilities and which are presented in this issue of the journal on recent patents on signal processing involve image processing, processing of voice signals, detection of speech impairments using mobile devices, video compression and video error resilience/concealment, optics communications, optimization of optical components such as MUX/DEMUX, distortion mitigation in transmitter systems and detection of handwriting impairment.
