In clinical pathology screening, scoring based on Immunohistochemistry staining ER, PR, Her-2 and Ki-67 are important indicators for evaluations of recurrence risk of breast carcinoma in addition to histological pathology of grading such as scoring based on tubule formation, Pleomorphism, and mitotic count. In this research, we extend the previous research results developed using a series of image...
This article looks at combining the Curvature Scale Space (CSS) shape matching algorithm and the Watershed Algorithm with the aim of creating a simple yet effective leaf identification software. The CSS shape matching algorithm solves the problems of: • Leaf self-intersection — Parts of a leaf overlap. • Leaf rotation — Images that are rotated. • Leaf variation — No two leaves are the same. The Watershed...
Traditional background modeling methods often require complicated computations and suffer from cavity problems in foreground objects. In this paper, we propose a block-based background modeling method combining multiple detection results derived from color and texture characteristics. This method can significantly alleviate the cavity problem and resist certain shadow interference. Since the proposed...
Images/videos of outdoor scenes are usually degraded by the turbid medium in the atmosphere. In this paper, a novel single image-based dehazing framework is proposed to remove haze effects from image/video, where we propose two novel image priors, called the pixel-based dark channel prior and the pixel-based bright channel prior. Based on the two priors with the haze imaging model, we propose to accurately...
In applications of the computer vision field, a vision system is usually composed of several low level and high level components, stacked on top of each other. A better design of the lower level components usually results in better accuracy of higher level functions, such as object tracking, face recognition, and surveillance. In this paper, we focus on the low level component design, background construction,...
In recent years, mobile phones have become very popular due to technology advances. However, unprotected personal photos and videos can easily be leaked when the phone falls into the hands of a malicious user. In this paper, we propose a multimedia privacy-preserving system for mobile phones. The system can protect information of the faces on the images or encrypt the whole image. Since most of the...
Due to the development of technology, electronics have become intertwined with our daily lives. Because of our reliance on such products, they need to be user-friendly, thus, improving current technology products is critical. One example of an electronic product with an opportunity for improvement is the projector. In many places, projectors have become an indispensable instrument for presentations...
Background construction is the base of object detection and tracking for the machine vision system. Traditional background modeling methods often require complicated computations and are sensitive to illumination changes and shadow interference. In this paper, we propose a block-based background modeling method, which fully utilizes the color and texture characteristics of each incoming frame. The...
With increasing number of aging people, taking care of the elderly will become more and more important for future society, especially for those elderly living alone. This paper presents an autonomous mobile robot Rola (Robot of LivingAid) , which can handle certain emergency conditions in a home setting to help the elderly through multi-modal sensing and control functions. The implemented functions...
