IEEE International conference on image processing

作者： thomas Maugey Pascal Frossard Signal Processing Laboratory (LTS4) École Polytechnique Fédérale de Lausanne Lausanne Switzerland

Research in multimedia is always investigating new ways of improving the immersive experience of the users. One current solution consists in designing systems which offer a high level of interactivity, such as multiview content navigation where the point of view can be changed while watching at a video sequence (e.g., free view- point television, gaming, etc.). the coding algorithm designed for the transmission of such media streams must be adapted to these novel decoder needs. However, video plus depth data transmission is usually performed by considering the information flows as two sequences encoded with MVC schemes. Whereas it achieves good compression performance, this coding approach is not appropriate for interactive applications since the decoding of a frame of- ten requires the prior transmission and decoding of several reference frames. Moreover, the techniques recently developed to improve interactivity are generally implemented at the decoder, whose computational complexity requirements are augmented. In this paper, we propose a novel coding scheme for video plus depth sequences that is adapted to user navigation; contrarily to several common approaches, the additional complexity is added on the encoder side so that the decoder stays simple. We further propose to limit the additional bandwidth imposed by interactivity requirements by designing a rate allocation algorithm that builds on a model of the user behavior. A first version of our novel coding architecture is evaluated in terms of rate-distortion performance, where it is shown to offer a high interactivity at a reasonable bandwidth cost.

International conference on Circuits, Communication, Control and Computing

India is home to 10% of all traffic deaths worldwide and has the second-largest road network in the world. Moreover, in smart cities, traffic congestion, pollutants, and noise pollution have increased due to a constant rise in vehicle kinds, technical problems with traffic signal management equipment, and inefficient road traffic management. Despite the fact that current traffic control systems rely on fixed time-based techniques, conventional traffic control systems are unable to manage the complicated traffic flow at junctions. Roadblocks increase mileage, increase transport costs, and pollute the air in addition to adding to the driver's stress and further delays. therefore, we designed a smart traffic light management system employing the recently launched YOLO V7. the new version V7 of the YOLO algorithm outperforms all previous object detection models in both speed and accuracy. As it is the fastest and most accurate real-time object detection model hence it is the best algorithm to deploy in traffic controlling system. YOLO V7 is +120 % faster than other previous models and shows the best speed to accuracy balance.

image processing now plays a relevant role in a wide range of fields. image registration, a critical aspect of image processing, encompasses essential issues like image fusion, and remote sensing. One of the most robust algorithms used in feature registration is the Oriented FAST and Rotated BRIEF (ORB). Several optimization methods, including random sample consensus (RANSAC), have been adopted to reduce the outliers in this algorithm ORB and find optimal parameters of the image registration problem. However, RANSAC-based methods exhibit some deficiencies such as a high number of iterations, increased false positives ratio of mismatches, and a fixed threshold value determined through experimentation resulting in lower accuracy of transform model parameters. In this paper, we propose a modified version of RANSAC incorporating a Median Absolute Deviation (MAD) based on an adaptive threshold to address these deficiencies. To verify the validity of our proposed approach, a comprehensive experimental analysis has been done on a database of two images. A study, of the influence of certain factors such as the angle of rotation of the sensed image, the scale of the sensed image, and the noise applied to the sensed image. the simulation results show that the proposed method can achieve good transform model parameters in terms of Mean Square Error (MSE), Structure Similarity Index Method (SSIM), and Peak signal to Noise Ratio (PSNR).

Reflecting various physical phenomena of the primary visual cortex (V1) in hierarchical approaches has become prevalent over the years when the semiconductor miniaturization reaches its limit. In this paper, we propose a V1 hardware model to extract features. Our architecture with the edge, slit, left-right parallax, XY movement direction, and approach detection functions are a partial mimic from V1. the fundamental of the model is the sum of absolute differences and the AND function of the slit angles, which are increased gradually every 22.5° in the range of 0° to 157.5°. the handwritten letter recognition application is the first application that is assessed by replacing the first convolutional layer with the slit detection function. Our model is evaluated on Xilinx Zynq-7020 FPGA by the Vivado HLS tool. We reduce 46% in latency and 30% hardware resources at a 97.34% accuracy with other works on the MNIST database. It is therefore suggested that the proposal demonstrates high-efficiency energy in the hardware architecture.

IEEE signal processing and Communications applications (SIU)

作者： Edmond Nurellari Erhan A. İnce Electrical and Electronic Engineering Eastern Mediterranean University Turkey

In this work, a concatenated forward error correction (FEC) scheme together with Orthogonal Frequency Division Multiplexing (OFDM) have been used for effective transmission of data/images over additive and fading channels. With a Bose Chaudhuri Hocquenghem (BCH) code as the outer code and a Low Density Parity Check (LDPC) code as the inner code, the transmission has been simulated over both the Gilbert-Elliot and ITU Rayleigh fading channels. the FEC parameters assumed throughout the simulations were obtained from the DVB-T2 standard and the Base Band (BB) frames were created by making use of shortening and zero-padding concepts. the results which have been presented in terms of BER and psycho-visual performances show the resilience of the FEC schemes and OFDM to channel impairments. the BER performances attained over the Gilbert-Elliot Channel (a channel that introduces burst errors when in the bad state) using LDPC only and BCH-LDPC concatenated coding indicated that the outer BCH coding will start to achieve a much lower BER after an SNR of 5 dB. Over the ITU-A Rayleigh fading channel it was observed that the performance increment due to the outer BCH encoder only become apparent after 6 dB when compared to the rate ¼ LDPC only coded system BER performance. Over the Gilbert-Elliot channel a BCH-LDPC coded QPSK-OFDM system would provide a BER of 3×10 -4 at 6 dB while the same BER for the ITU Vehicular-A channel was possible at 6.6 dB.

Traditional no-reference image quality assessment algorithms mostly focus on the objective indicators of the image, such as the IE (information entropy) and clarity of the image. these indicators can reflect the quality of the image at the objective level to a certain extent, but it cannot well reflect the human visual evaluation of the image. In fact, it's still a relatively difficult problem to obtain the human visual evaluation of the image through a no-reference image quality assessment algorithm, considering the complexity of the imaging mechanism of the HVS (Human Visual System), for example, the connection mode of photoreceptor cells and ganglion cells which still cannot be well expressed by any specific model, along with the individual differences of human visual perception. this paper starts with the perception process reconstruction of the HVS, uses the similarity between the reconstructed image and the original image to reflect whether the image conforms to the request of human visual perception, carries out parameter optimization and correlation verification. Finally, it is found that the proposed algorithm has better relevance, lightness and universality than the existing algorithms, and can more effectively restore the scoring result of human visual perception of the test image.

Due to the design requirements for miniaturization and high-density placement of silicon photonics (SiPh) components in integrated circuit (IC) packaging, the system in package (SiP) process and equipment have become important but challenging. Automatic optical inspection (AOI) detection equipment in IC packaging lines is also important in identifying redistribution layer (RDL) anomalies that affect signal transmission. If the AOI misrecognition rate is too high, the production yield and overall equipment performance are lowered. To solve the above problems, we proposed a novel Pix2Pix generative adversarial network (GAN) algorithm based on machine learning methods. the new feature extraction method has demonstrated highly sensitive image detection capabilities after processing tens of thousands of huge SiPh RDL image databases.

In this paper we study tomographic reconstruction methods in the case that prior knowledge about the object is available. In particular, we consider the case that a reference object that is similar in shape and orientation is available, which is very common in non-destructive testing applications. We demonstrate that a differential version of existing reconstruction methods can easily be derived which reconstructs only the deviation between test and reference object. Since this difference volume is significantly more sparse, the differential reconstruction can be implemented very efficiently. We also discuss the case where knowledge about the misalignment between test and reference object is available, in which case the efficiency of the differential reconstruction can be improved even further. the resulting algorithm is faster, more accurate, and less sensitive to the choice of the step size parameters and regularization than state of the art reconstruction methods.

the mission of parking attendants includes several tasks. One can mention, the supervision of automobile access, the management of parking facility, and the promotion of parking areas safety. therefore, an intelligent system which allows carrying out some tasks only by speaking will definitely help attendants to complete their mission properly. the solution we propose activates the main computer to listen and promptly recognizes commands spoken in Arabic by the parking attendant in real-time. It seamlessly performs various tasks, including (i) opening and closing the main barrier, (ii) controlling the lights in the parking area automatically, and (iii) triggering and stopping theft alarms. the solution is based on two main phases: (i) querying the computer in real time through an impulsive waveform such as hands clapping, (ii) and recognizing voice commands. the first phase is accomplished using impulsive sound identification technique based on normalized version of power sequences. However, the second phase uses Google's application programming interface. the software was designed using Python language. We controlled external hardware such as parking barrier, light bulb, and alarm device using Arduino board. the execution time of the proposed software is nearly real-time and ranges from 5 to 6 seconds. the average subjective evaluation score conducted by 6 users is 4/5.
