In order to improve the elïïciency of apple's grading and ensure the scientilïcity and objectivity of grading, this paper presents a three-stage grading system, namely weighing grading, color grading and shape grading. Hardware design uses high-performance S3C2440 embedded controller, DSP controller, single-chip micro-processor controller, pressure load sensor, color recognition sensor, graphic recognition...
One of the challenges in children education is the inclusion of students with Down syndrome in regular schools. Some studies have discussed the advantages of using technological resources as mediation tools in literacy processes, as well as the impact of these resources in the distance education modality. However, an issue identified in the current state of the art is the lack of initiatives related...
This article contains a new alternative to the nondestructive hyperspectral analysis of the fermentation process of the cocoa bean. The study focuses on the chemical changes of the bean, measured along the eight days of fermentation in the wood boxes, and relating it to a new hyperspectral index. The study compares several beans looking for a new index, obtaining, for each index, a variety of curves...
In this study, it is A web-based image processing software which has been introduced to process Immunohistochemical images obtaining in experimentally induced diabetic rats and rank the severity of diabetes between the groups. With the software, specialist physicians can upload Images obtaining in rat groups to the system via web on own account, obtain average color intensity and intensity graphs...
This paper presents a digital image processing software implementation to identify and study models of infection related to Chagas disease caused by Trypanosoma cruzi parasite. The main objective is predicting disease progression to decide the appropriate treatment depending on the tissue damage observed and evaluate the effectiveness of these treatments in diminishing the structural alterations....
In these days, Social Networking Sites (SNS) are indispensable tools for communication in our life. However, it cannot be said that all of the dominant SNS have sufficient expressive ability. Insufficient expressions lead to misunderstanding and causes human-relation troubles. To solve this problem, we focus on "Fonts." Fonts have an important role in communication by texts. In this paper,...
This paper investigates brain signal peaks and their relationship to flicker size and resolution using colour red-white (RW) and monochrome black-white (BW) graphics. The raw electroencephalograph (EEG) signals were recorded using Emotiv EPOC headset into Windows based PC running Emotiv Xavier Test Bench software. The flickers oscillating at 10 Hz of different resolutions were displayed over black...
This paper proposes a color attribute compression method for MPEG Point Cloud Compression (PCC) by exploiting the spatial redundancy among the adjacent points. With the increased interest in representing real-world surface as 3D point clouds, compressing the attributes (i.e., colors and normal directions) of point cloud has attracted great attention in MPEG. The proposed method is based on grouping...
The artificial vision is a part of the artificial intelligence that pretends to simulate the human vision, is to say, from the acquisition, processing, analysis and interpretation of images through an intelligent system. This work presents the creation of prototypes under the game jam model as a software product. In this context, the objective of the present work was to apply basic artificial vision...
In image processing area and segmentation algorithms based on thresholding, the intensity of the image (grayscale) is usually obtained in order to differentiate the regions of the objects and the background. The segmentation based on the threshold works well when the image has a high intensity in the contrast, this characteristic is key to make a good classification of the pixels. This document will...
The recent advances in light field imaging are changing the way in which visual content is captured, processed and consumed. Storage and delivery systems for light field images rely on efficient compression algorithms. Such algorithms must additionally take into account the feature-rich rendering for light field content. Therefore, a proper evaluation of visual quality is essential to design and improve...
The new Ultra High Definition (UHD) standard digital imagery can represent much more color information than High Definition (HD) and Standard Definition (SD). Currently most manufactured displays support UHD colors while UHD is being deployed for content production. However not all service providers have updated their pipeline thoroughly. Thus, the enduser that buys a UHD display would not be able...
The process of drawing is one of the main activities during childhood. The drawing dynamics, drawing techniques are on the focus of education science. It is known that the result of the drawing process depends on eye-hand coordination. Testing of the psycho-motoric reactions allows classifying motion and positioning problems. Psychomotor reaction data, compared with the characteristics of the drawing...
Immunohistochemical (IHC) markers viz., estrogen receptor (ER), progesterone receptor (PR) and proliferation marker Ki-67 are widely used for prognostic evaluation of breast cancer. The goal is to quantify the stained cells which are used to comment on the severity of cancer. In general, the expert pathologist performs the visual assessment task which is obviously tedious, time consuming and prone...
Wide-area visualization tool using synchrophasor information is considerably essential for monitoring and understanding power grid dynamic behaviors. In this paper, a plug-in software application tool for wide-area visualization has been developed to complement the commercial software tool that has the limited display capabilities. The enhanced trending charts and color contour map visualization created...
Quinoa is an Andean grain with high protein content that has achieved, in recent years, a great acceptance in the international market. However, the presence of saponin and its toxicity in the grain surface makes necessary its elimination for human consumption. This article deals with the elimination of saponin in fluidized bed for the bitter Chimborazo quinoa, with an initial saponin content of 0...
The implemented system automatically capable of annotating images of a database based on samples. The system creates annotations to images with detection of the object belonging to the keyword. The set of keywords is predefined. After the user searching the first twelve relevant results will be showed. Due to the higher accuracy of the system, the user has to comment results then the system has to...
Program comprehension procedure have been attracted a lot of attentions and have been investigated using a variant methodologies such as thinking aloud, summary analysis, and Eye-tracking. Program comprehension tools main objective is understanding source code which is substantial factor in software maintenance activities. Visualization is a popular approach in earning this understanding. This paper...
Manga (Japanese comics) are popular all over the world, and are created digitally. In this paper, we propose an interactive segmentation method tailored for manga. The proposed method enables annotators to select areas in manga efficiently. Our experimental results showed that the proposed framework works better than Adobe Photoshop CC, which is the most widely used commercial image editing software.
Based on the analysis of the types and characteristics of Chinese traditional paper-cut patterns, we propose a new algorithm for extracting and vectoring the patterns. On the contour extraction, the algorithm uses a grayscale, binary, contour tracking method. On the vectorization, we improved the segment Displaced curve segments so that you can make the final contour paper cutting pattern vector into...
