The combined use of mice that have genetic mutations (transgenic mouse models) of human pathology and advanced neuroimaging methods (such as MRI) has the potential to radically change how we approach disease understanding, diagnosis and treatment. Morphological changes occurring in the brain of transgenic animals as a result of the interaction between environment and genotype, can be assessed using advanced image analysis methods, an effort described as "mouse brain phenotyping". However, the computational methods required for the analysis of high-resolution brain images are demanding. In this paper, we propose a computationally effective cloud-based implementation of morphometric analysis of high-resolution mouse brain datasets. We show that the proposed approach is highly scalable and suited for a variety of methods for MR-based brain phenotyping. The proposed approach is easy to deploy, and could become an alternative for laboratories that may require instant access to large high performance computing infrastructure.

Dermatological diseases are the most prevalent diseases worldwide. Despite being common, its diagnosis is extremely difficult and requires extensive experience in the domain. In this research paper, we provide an approach to detect various kinds of these diseases. We use a dual stage approach which effectively combines computervision and Machine Learning on clinically evaluated histopathological attributes to accurately identify the disease. In the first stage, the image of the skin disease is subject to various kinds of pre-processing techniques followed by feature extraction. The second stage involves the use of Machine learning algorithms to identify diseases based on the histopathological attributes observed on analysing of the skin. Upon training and testing for the six diseases, the system produced an accuracy of up to 95 percent.

Using fixed order fractional differential for image enhancement, some regions of the image may not achieve the desired enhancement effect. According to the characteristics of human vision and low illumination image, an adaptive order fractional differential enhancement algorithm is proposed. Three different differential orders are selected for enhancement, and one of them is adaptively selected for each pixel according to the comparison results of gradient values. The experimental results show that the adaptive order can not only enhance the image with high gradient value such as the edge, but also reduce the noise interference in the flat area,which has better visual effect than fixed order enhancement.

Fires are one of the main causes of death amongst the world. Although there are various fire detection systems most of them did not proof its effectiveness in detecting fires due to inefficiency or restrictions. For example, systems based on smoke sensors in detecting fires cannot be used in open areas because they are restricted to the existence of a ceiling or a wall. Besides that, having many flammable objects in open large areas, such as trees and fuel of car may interact with oxygen in the air which make fire growth and expansion very fast. According to the prior stated facts in this paper we present the project we worked on with the aim of implementing a more efficient and trustworthy fire detecting system. The project was done by using computervision and imageprocessing techniques to detect fire flames based on studying the fire properties besides an alarm notification system.

Robotics technology has merged into human's ev-eryday life, from industry to domestic application, including agriculture and creates digital farming. Agriculture industry currently faces new challenges, including aging farming and higher demand for food to feed the growing population. It is expected that robot application in agriculture can reduce the production cost in the long run and improve product quality, and increase productivity. A robot can be applied from seeding, maintenance, crop harvesting, and packing. A pick and place robot is an ideal form in accumulation and packing the harvested product. This type of robot a vision sensor to detect the crop to be collected or object to be picked and placed. However, the application of imageprocessing needs to be kept adequate but straightforward to accommodate the current microcontroller technology. This paper discusses the implementation of an edge detection method for recognizing and tracking an object, and the target considered in this study is a tomato. Twenty experiments were conducted to pick and place a tomato from 3 random positions to a basket. The total average time of robot to finish its task is 05.81 s. The experimental result shows that the proposed method is effective for a 4DOF pick and place robot.

The detection of mobile 3-D objects using both stereovision and motion information is considered. First, the authors present an optical flow estimation method based on a multiresolution technique for the matching of contour chain points. Then an algorithm of segmentation of the chains using the continuity of the gradient of the apparent velocity is described. A similar algorithm is developed for stereo vision: the segmentation of the chains is performed in function of their 2-D proximity and the continuity of their disparity. These two segmentations are then used to interpret the scene in terms of isolated rigid or deformable objects. Results are shown for two complex real road scenes.
