The complex estimation of complexity algorithms at application Ateb-Gabor filtration is developed. This filtration is proposed to be used for biometric images. Gabor filtration is a reconstruction of a biometric image multiplying the harmonic function by the Gaussian function. Ateb-functions are an extension of trigonometric functions, and therefore have more functionality. The efficiency of using the Ateb-filter function is shown, which consists of more variants of processed images. Experimental researches of working out filtering time by the developed filter are carried out. The Ateb-Gabor filter contains two rational parameters m and n that allow you to get new values and get new features when filtering. Changing the m and n parameters provides new values for the Ateb-Gabor period, which allows you to extend the number of filter options.

Applications for face detection use algorithms that rely on identifying human faces in broader photos that may include environments, artifacts, and other sections of a person's physique. This work proposes a real-time identification system, based on modern imageprocessing capabilities of open source API like OpenCV and due to the solution requirements, a study on the performance analysis of such solution compared to available commercial framework like SPID from NEC is intended. However, here, the study is available with the results of various experiments on the developed system. A systematic approach is followed to produce such outputs and have been measured using software codes. By using IP camera and a Raspberry Pi, the solution developed is simple in nature. This study relies on face detection and identification functionalities for human faces but not limited to live faces only but mix of faces from still images as well.

Reversible logic synthesis and testing is a fascinating research area as it is an important approach for low power design and quantum computing. Reversible computations have different applications such as quantum computing, nanotechnology, digital signal processing, bio-information etc. All these applications require a cryptography system to restrict the unauthorized access and thus maintain the confidentiality of data. High area and power requirements are some of the major problems of well secured cryptography algorithms. In this work, a Reversible Logic Gates Cryptography Design (RLGCD) is proposed to overcome these problems. RLGCD is used to design both encryption and decryption architectures. Linear Feedback Shift Register is used to generate the key for encryption and decryption processes. To further improve the security of data watermarking is done using Least Significant Bit (LSB) method. The FPGA performance of RLGCD architecture is evaluated. There is a great improvement in the performance of RLGCD architecture when compared to other conventional systems.

We present a new multi-robot system as a means of creating a visual communication cue that can add dynamic illustration to static figures or diagrams to enhance the power of delivery and improve an audience's attention. The proposed idea is that when a presenter/speaker writes something such as a shape or letter on a whiteboard table, multiple mobile robots trace the shape or letter while dynamically expressing it. The dynamic movement of multi-robots will further stimulate the cognitive perception of the audience with handwriting, positively affecting the comprehension of content. To do this, we apply imageprocessingalgorithms to extract feature points from a handwritten shape or letter while a task allocation algorithm deploys multi-robots on the feature points to highlight the shape or letter. We present preliminary experiment results that verify the proposed system with various characters and letters such as the English alphabet.

imageprocessing plays a crucial role in our day to day life as it is helpful to solve important problems in real world. Recent progress in quantum information and computation led to the birth of a new field called Quantum imageprocessing. This new field of imageprocessing in quantum domain focuses on the development of the quantum imageprocessingalgorithms, which can run more efficiently on quantum computer. These quantum algorithms are better in terms of image storage and retrieval with reduced computational complexity. In this article we present recent advancements in quantum image representation with different mathematical models and with their corresponding computational complexity.

A challenge in applying imageprocessingalgorithms to scientific data is the variation within and across images in a data set. This makes it difficult to select parameters for the algorithms, especially when the data set is large and the variation is unknown. Using the task of segmentation of retinal images, we discuss the challenges that arise in selecting parameters for even a relatively simple algorithm. We show that the availability of ground truth results could make the identification of parameters subjective and propose a simple idea that could benefit the selection of a single parameter.

The assumption of static scene is typical in SLAM algorithms, which limits the use of visual SLAM systems in real-world dynamic environments. Dynamic elimination, detecting or segmenting the static and dynamic region in the image and regarding the features in dynamic parts as outliers, is proved to an effective solution to solve the dynamic SLAM problem. However, traditional dynamic elimination methods processing each frame are very time consuming. In this paper, dynamic elimination is implemented only on keyframes utilizing YOLO as the fast dynamic detection network. This keyframe-based improvement ensures localization accuracy by ensuring map accuracy, and at the same time increases the speed of the SLAM system with dynamic elimination greatly. Experiments are conducted both in real-world environment and on the public TUM datasets. The results demonstrate the effectiveness as well as efficiency of our method.

FPGAs provide a flexible and efficient platform to accelerate rapidly-changing algorithms for computer vision. The majority of existing work focuses on accelerating image classification, while other fundamental vision problems, including object detection and instance segmentation, have not been adequately addressed. Compared with image classification, detection problems are more sensitive to the spatial variance of objects, and therefore, require specialized convolutions to aggregate spatial information. To address this, recent work proposes dynamic deformable convolution to augment regular convolutions. Regular convolutions process a fixed grid of pixels across all the spatial locations in an image, while dynamic deformable convolutions may access arbitrary pixels. The access pattern of deformable convolutions is input-dependent and varies per spatial location. These properties lead to inefficient memory accesses of inputs with existing hardware. In this work, we first investigate the overhead of the deformable convolution on embedded FPGA SoCs, and then show the accuracy-latency tradeoffs for a set of algorithm modifications, including full versus depthwise, fixed-shape, and limited-range. These modifications benefit the efficiency of the embedded accelerator in general. We build an efficient object detection network with modified deformable convolutions and quantize the network using state-of-the-art quantization methods. Experiments show that our co-design optimization for the deformable convolution achieves significant hardware speedup with little accuracy compromised.
