Abstract Beekeeping plays an important role in increasing and diversifying the incomes of many rural communities in Kingdom of Saudi Arabia. However, despite the region’s relatively good rainfall, which result in better forage conditions, bees and beekeepers are greatly affected by seasonal shortages of bee forage. Because of these shortages, beekeepers must continually move their colonies in search of better forage.... Beekeeping plays an important role in increasing and diversifying the incomes of many rural communities in Kingdom of Saudi Arabia. However, despite the region’s relatively good rainfall, which result in better forage conditions, bees and beekeepers are greatly affected by seasonal shortages of bee forage. Because of these shortages, beekeepers must continually move their colonies in search of better forage. The aim of this paper is to determine the actual bee forage areas with specific characters like population density, ecological distribution, flowering phenology based on colour satellite image segmentation using K-mean clustering. K-mean segment region satellite images into five segments, following that we search in a sample of acacia trees against this image clusters to specify the best region for better forage.

Abstract This paper presents a simple and effective approach for target detection in sea images. In this regard, three renowned detection methods which are SVM, edge and corner detectors have implemented. They have been applied on an image independently, and then a combination between detected points have been made by sliding a 20×20 matrix. To decrease the false positives and to... This paper presents a simple and effective approach for target detection in sea images. In this regard, three renowned detection methods which are SVM, edge and corner detectors have implemented. They have been applied on an image independently, and then a combination between detected points have been made by sliding a 20×20 matrix. To decrease the false positives and to increase the efficiency of final detection results, connected component labelling has been applied to the output of each detector to eliminate small connected components. Testing the proposed method on two different databases of sea target images shows its efficiency in target detection. Read More Read Less

Thanks to the development of information technology, fraud has multiplied, and many protection techniques have emerged to improve the security of our information, such as encryption, steganography and watermarking. In this paper we will present a novel scheme to secure multimedia information. Our aim is to increase the security of transmitted signals. First we improved an encryption algorithm based on chaotic iteration of the Logistics map. Then, we developed an algorithm to watermark information by using DCT method to insert message. Simulations and discussions of our method are presented to prove the efficiency of our proposition. Read More Read Less
