This paper covers the design of a complementary metal oxide semiconductor (CMOS) pixel readout circuit with a built-in frequency conversion feature. A single pixel was designed containing all of the signal-to-frequency conversion circuitry, after which an array of 64 pixels was designed. The on-chip frequency modulation technique is preferred over analog-to-digital conversion (ADC) techniques due...
This paper presents the new approach for building agile antenna beam forming ARMA. The concept of this antenna is based on the pixel derived from electromagnetic band-gap material antenna. ARMA was published in many papers concerning the linearly polarized agile matrix antennas that show the performances and the interest of this new approach in comparison with the classical agile antennas. In this...
To achieve better and faster material discrimination in applications like security inspection, X-Ray image sensors giving a highly resolved energy spectrum per pixel are required. In this paper, a new pixel architecture for spectral imaging is presented, exhibiting a 256 bin spectrum per pixel in a single image duration, up to two orders of magnitude higher than previous works. A prototype circuit,...
In this paper, we will discuss the Quality of Edge Detected at different threshold values. For the purpose we will compare among Bacterial Foraging Algorithm, Canny Edge detector and Sobel Edge Detector. The Algorithm Bacterial Foraging also uses a thickness constraint and follows the Swarm intelligence feature and works like the behavior of bacteria in the search of food, Whereas Canny uses eliminates...
The article outlines the publications on measuring the field of vibration movement of the surface of the controlled object. The authors have conducted the modelling of the trace of vibration-induced image blurring with the aim of determining structural parameters that are the input data for calculating the vector components of the vibration movement of the studied material point. The article describes...
Automated classification algorithms have been applied to breast cancer diagnosis in order to improve the diagnostic accuracy and turnover time. However, classification accuracy, sensitivity and specificity could still be improved further. Moreover, reducing computational cost is another challenge as the number of images to be analyzed is typically large. In this paper, a novel Pixel N-gram approach...
For secure data transmission over internet, it is important to transfer data in high security and high confidentiality, information security is the most important issue of data communication in networks and internet. To secure transferred information from intruders, it is important to convert the information into cryptic format. Different methods used to ensure data security and confidentiality during...
Object tracking in real time is one of the most important topics in the field of computer Vision. The work undertaken in this dissertation is mainly focused on development of a reliable and robust real time tracking system that can track the object of interest in the video acquired from a stationary or moving camera. The proposed algorithm is a real time algorithm that operates in 25 frames per second...
Due to the application requirement of single source tracking in dynamic background, it is difficult to get accurate pedestrian target detection. Through comparing performance quality of pedestrian describing operator between CENTRIST and HOG, we adopt CENTRIST feature extraction to combine with SVM off-line classifier and to train off-line model for target detection. Furthermore, we propose the importance...
Communication between devices and data through networks have been increasing drastically in the past few decades. Encryption of data provides high level of security. This paper presents a median based technique for selective encryption where partial data of image is encrypted based on pixel values. An encrypted mask of the image is also appended with the image that specifies the pixels that are encrypted...
This work addresses the study of active edge n-in-p planar sensors. Active edge planar pixel sensors are promising candidates to instrument the inner layers of the new ATLAS pixel detector for High Luminosity Large Hadron Collider (HL-LHC), thanks to its radiation tolerant properties and the increased fraction of active area due to a distance as low as 50 μm between the last pixel implants and the...
A number of approaches have been developed for image steganography till date but none have used quadtree partition scheme. The quadtree partition is used to divide the image on the basis of variations among the pixel values and therefore we can identify the fine grained and coarse grained areas inside the image. It is very much comfortable and effective to hide something in the roadside scrub rather...
The fingerprint pixel sensor array was investigated for the application to the mobile phone. For the fingerprint sensing high resolution pixel array is necessary. Therefore, the readout voltage dependence on the resistance of the wires was investigated after composing 450th pixel array. The readout voltage was investigated for the ridge contact and valley contact. The simulated results show that the...
In this paper FPGA implementation of a simple median based technique for selective image encryption is presented. Image encryption imposes heavy resource requirements on the hardware platform due to large size of data. Although Advanced Encryption Standard (AES) provides a high level of security to the image, it takes more time when used for image encryption. The technique presented in this paper...

The pixel concept was published in many papers concerning the agile radiating matrix antenna. In this paper we study the pixel generating circularly polarized field. This study will be the main step to introduce agility in beam forming of the matrix antenna for the space...
Various statistical methods such as co-occurrence matrix, local binary patterns and spectral approaches such as Gabor filters have been used for generating global features for image classification. However, global image features fail to distinguish between local variations within an image. Bag-of-visual-words (BoVW) model do capture local variations in an image, but typically do not consider spatial...
Next generation of pixel detectors for the first layers of the ATLAS and CMS experiments at the High-Luminosity Large Hadron Collider (HL-LHC) are expected to sustain the particle flow rates up to ∼2 GHz/cm2. The very high radiation levels and small available space makes it impossible to envisage optical conversion on chip, which should be done using electrical links, implying that a significant material...
