This paper is a development of the iGePVO-K method by discarding the sequence of binary flags. That means it is not necessary to embed flags with the data in the original image. Therefore, the proposed method not only has a larger data embedding capacity but also has a better image quality than the methods mentioned above.

This book is intended as an introduction to computer vision for a broad audience. It provides necessary theory and examples for students and practicioners who will work in fields where significant information must be extracted automatically from images. The book should be a useful resource book for professionals, a text for both undergraduate and beginning graduate courses, and a resource for enrichment of college or even high school projects. Our goals were to provide a basic set of fundamental concepts and algorithms and also discuss some of the exciting evolving application areas.

Bài viết đã xem xét ba loại mô tả đặc trưng, như Local Binary Patterns (LBP), Histogram of Oriented Gradients (HOG) và Gradient Domain Image Stitching (GIST) để mô tả hình ảnh hạt lúa giống. Tuy nhiên, cách tiếp cận này làm nảy sinh vấn đề về hiện tượng số chiều và cần phải lựa chọn các đặc trưng liên quan để có một mô hình biểu diễn nhỏ gọn và tốt hơn.

The experiments are conducted on irregular microscopic images (where variations in size and shape occur) in the binary classes of healthy and sick cases related to OPMD. The proposed framework achieves a higher accuracy rate for the detection as compared to other methods, and exhibits a detection strategy for other types of PCD in medical applications.

In a simple but effective manner, convolutional neural networks (CNNs) are proposed to exploit their well-known advantages on images for temporal educational data. As a result, the task is resolved by our enhanced CNN models with more effectiveness and practicability on real datasets. Our CNN models outperform other traditional models and their various variants on a consistent basis for program-level student classi¯cation.

In this article, we present the development of a novel technique that is used to enhance the detection of micro cracks in solar cells. Initially, the output image of a conventional electroluminescence (EL) system is determined and reprocessed using the binary and discreet Fourier transform (DFT) image processing models.

The current study proposes a novel binary catalyst system (composed of metal/metal oxide nanoparticles) as a promising electrocatalyst in formic acid oxidation. The electro-catalytic oxidation of formic acid is carried out with binary catalysts of Pt nanoparticles (nano-Pt) and manganese oxide nanorods (nano-MnOx) electrodeposited onto glassy carbon (GC) electrodes. Cyclic voltammetric (CV) measurements showed that unmodified GC and nano-MnOx/GC electrodes have no catalytic activity. While two oxidation peaks were observed at nano-Pt/GC electrode at ca. 0.2 and 0.

This paper presents a hardware module design for the forward Binary Discrete Cosine Transform (BinDCT) and its implementation on a field programmable gate array device. Different architectures of the BinDCT module were explored to ensure the maximum efficiency. The elaboration of these architectures included architectural design, timing and pipeline analysis, hardware description language modeling, design synthesis, and implementation.

This paper proposes a new multiclass approach called multi-level (hierarchical) learning architecture (MLA). It addresses the binary classification tasks within the framework of a hierarchical strategy. It does so by accounting for the interaction between several classes and the domain knowledge.

In this paper, an object detection approach for high-resolution binary images is proposed without scanning all the pixels in the images. Here, elliptical object detection is considered, pixels on horizontal and vertical parallel lines are scanned keeping a constant gap between each two lines.

This paper is about a algorithm used for edge detection using logical operations. First image is converted into binary image and then it is rotated left, right, up and down. Afterwards logical AND operation is performed between rotated and original image and results are stored in different variables.

This paper simulates an effective data hiding technique i.e. steganography based on LSB insertion and RSA encryption in order to provide seven million times better security than the previous work. The Main idea of proposed scheme is to encrypt secret data by RSA 1024 algorithm, convert it in to binary sequence bit and then embedded into each cover pixels by modifying the least significant bits (LSBs) of cover pixels. The result image is also known as steganography image.

In this work, the final binary SAMs composed of 11-aminoundecanethiol (AUT) domains and 10-carboxy-1- decanethiol (MUA) domains on Au(111) substrate was used for immobilizing chicken liver sulfite oxidase (CSO) to study the direct electron transfer and detect sulfite anions. Scanning tunneling microscope images clearly showed the phase separation between AUT and MUA domains in the final binary SAMs prepared by the electrochemically selective replacement method.
