Traffic sign recognition is an important step for integrating smart vehicles into existing road transportation systems. In this paper, an NVIDIA Jetson TX1-based traffic sign recognition system is introduced for driver assistance applications. The system incorporates two major operations, traffic sign detection and recognition. Image color and shape based detection is used to locate potential signs...
Saliency detection in images attracts much research attention for its usage in numerous multimedia applications. In this paper, we propose a saliency detection method based on optimization for RGBD images. With RGBD images, our method utilizes the depth channel to enhance the identification of background and foreground regions. We firstly generate new depth image by using non-linear transformation...
Neural Style Transfer has shown very exciting results enabling new forms of image manipulation. Here we extend the existing method to introduce control over spatial location, colour information and across spatial scale. We demonstrate how this enhances the method by allowing high-resolution controlled stylisation and helps to alleviate common failure cases such as applying ground textures to sky regions...
Single feature of pedestrian is difficult to accurately describe the target using traditional algorithms. A new reidentification algorithm combing global features and local features with different distance metric function is introduced. First, weighted color histogram feature for whole pedestrian is extracted and combined with Bhattacharyya distance to roughly recognize targets. Then pedestrians’...
The last years have seen a quick rise of digital photography. Plenoptic cameras provide extended capabilities with respect to previous models. Multi-focus cameras enlarge the depth-of-field of the pictures using different focal lengths in the lens composing the array, but questions still arise on how to select and use these lenses. In this work a further insight on the lens selection was made, and...
Image matting techniques are a key step of image processing or video editing, which is widely used nowadays. So, it has a highly demanding on processing speed. Since it usually takes a long time to process images using existing image matting algorithms, especially in high-resolution images or videos, this paper proposes a state-of-art image matting speed-up method to solve the slow-processing problem...
In this paper, we proposed a seam carving based refinement method to refine and produce superpixels. The proposed method can refine existing superpixels by repeating the splitting process. There are two major steps. The first is choosing a superpixel candidate by analyzing color variances; the second is splitting a superpixel into 4 by dynamic programming. The experimental results show that the proposed...
In this paper, a new method with visual saliency detection for image quality assessment (IQA) is proposed. Through the experiments in this paper, we have verified the proposed method can be effective than most others.
Image matting is one of the most common image processing techniques, because it is often necessary to extract the desired foreground object from the original image and then to composite the extracted foreground with the another background. Over the years, there have been lots of commercial image processing tools or softwares which can support the human beings this function, such as photoshop, photoimpact...
Social media platforms provide rich signal sets to understand the nature of social life, and sentiment analysis techniques have been developed to understand the emotional content of text from sites like Twitter and Facebook. Beyond text however, most social media platforms have images at their core, and communication of images may require quantization. Here, we develop methods and present results...
Recent years have witnessed a drastic rise in the number of image content on the Internet. In this context, several digital watermarking techniques have been investigated in order to prevent illegal duplication and distribution of such content. Illegal users in turn attempt to remove digital watermarks from such content, and collusion-attacking methods, such as an average value attack, constitute...
Image segmentation is an important technique in image processing. It be used for separating the objects or foreground from the background. This paper focuses on the split step of a split-and-merging approach for color image segmentation. For splitting, we propose a quad-tree method based on hue angles (QTHA). The QTHA introduces a novel metric criterion for measuring hue homogeneity within a block...
Vectorization is happened by a wave method. The wave method is to analyze the path of the way to the spherical wave in the image. At every step is analyzed offset center of point's mass forming a new step wave relative to the previous position of the center of mass. Offered of the perfected wave tracing algorithm is to use a spherical wave on the combined raster image while creating skeleton. The...
For a long time, color has always played a secondary role both in purely artistic or professional design. Although each creator is deeply aware and convinced that the color in addition to the creation of the moment with the unparalleled importance, the general viewers of the psychological and thoughts of the infectivity, it is not to mention. But these cognition, only to understand the color of the...
Aesthetic patterns are formed into different systems due to different regional customs, and the language of the contemporary presented by a work could be understood by aesthetics analysis. Poster is a printed media that massively passes messages to the public, it works like a barometer to reflect politics, economics, cultural and arts events of each period in timely manner, and this is particularly...
In the production of bulk materials or thin films, scientists usually seek to know about the geometric features of grains and some statistical properties of the material through the SEM image. Especially, the area ratio of grain to grain boundary plays an important role in applications. Some basic properties such as density, dielectric constant, hydrophobicity, hydrophilicity, piezoelectric constant,...
The visual image design of Olympic Games is an crucial task for each hosting country for which embodies the connotation of the Olympic games. The visual image design of 2016 Rio Olympic Games not only expressed the eternal Olympic spirits, but also conveyed the special understanding on Brazil's Rio Olympic Games. The construction of stadiums, opening ceremony and rewarding medals, communicated its...
Region merging is one of important steps in an image segmentation system, which can be used for partitioning the objects in images. This paper presents a region merging method based on hue angles (RMHA). The RMHA employs the architecture of the Improved Quad-tree Method (IQM) [7]. We propose the homogeneity testing based on hue angles (HTHA) as the core of the IQM. The HTHA merges two adjacent regions...
With the advance of information technology, video on the web (such as, Youtube) had been a common and convenient channel for learning by students. But the characteristics of transient information in videos are easy to impose a high cognitive load to students, especially for elementary school students. Because video is not a single text or a single image, which has rich colors and complex scenarios...
Rice Planthopper (RPH) infestation in paddy field is a serious disaster in Asia every year. Finding RPHs based on image processing is an important thing before RPHs growth. We propose a region of interest (ROI) method to detect RPHs clearly. First, get rectangle ROI in HSV space and do color analysis. By using decision tree algorithm, classify analytic data to get binary image of RPHs. The results...
