Digital watermarking has developed immensely for multimedia uses in the current decade. The requirement for protected digital content grows vital with the enhancement in exchange of digital images on internet. Watermarking is a technique to safeguard digital media by retaining the owner's possession. Fingerprinting extends the watermarking concept by embedding unique purchaser's information. This paper presents a joint digital watermarking and fingerprinting approach for colored digital images applied in double DCT domain. The approach aims at copyright protection and traitor identification of digital images. Altered mid-frequency coefficients are analyzed by applying forward DCT transform. Watermark and fingerprint are embedded in a non-overlying manner. Second DCT allows for the precise determination of the block, for embedding data. The double domain can enhance the embedding capacity of the host image by choosing more than one coefficients in a given block. Simulation outcomes reveal that the watermark is immune to JPEG compression, additive noise and median filtering. Quality of the image is retained, as the results reveal a Peak Signal to Noise Ratio (PSNR) in range of 58-73 dB.
Objectives The key test in Content-Based Medical Image Retrieval (CBMIR) frameworks for MRI (Magnetic Resonance Imaging) pictures is the semantic hole between the low-level visual data caught by the MRI machine and the elevated level data seen by the human evaluator. Methods The conventional component extraction strategies centre just on low-level or significant level highlights and utilize some handmade highlights to diminish this hole. It is important to plan an element extraction structure to diminish this hole without utilizing handmade highlights by encoding/consolidating low-level and elevated level highlights. The Fleecy gathering is another packing technique, which is applied in plan depiction here and SVM (Support Vector Machine) is applied. Remembering the predefinition of bunching amount and enlistment cross-section is until now a significant theme, a new predefinition advance is extended in this paper, in like manner, and another CBMIR procedure is suggested and endorsed. It is essential to design a part extraction framework to diminish this opening without using painstakingly gathered features by encoding/joining low-level and critical level features. Results SVM and FCM (Fuzzy C Means) are applied to the power structures. Consequently, the incorporate vector contains all the objectives of the image. Recuperation of the image relies upon the detachment among request and database pictures called closeness measure. Conclusions Tests are performed on the 200 Image Database. Finally, exploratory results are evaluated by the audit and precision.

Agriculture plays an important role in the economic development of a country. If proper care is given to the growth of crops, it returns to the efforts put in by farmers throughout the year. However, since past few years it is observed that the quality and production of crops are degrading due to the diseases caused by some biotic and abiotic agents. It is deemed necessary to detect crop diseases in time. Conventional methods of identifying a crop disease require a dedicated individual or an expert who can manually detect such diseases. But it is very time consuming process and increases the cost too. Here arises the need to develop automated systems that cannot only detect the plant diseases but saves time and cost. This manuscript will reflect the comparative analysis of classification techniques in terms of accuracies and will help the researchers to identify best practices for their research so as to enhance the efficiency and accuracy of diseases detection systems being developed.
Perceptible watermarking system is an imperative copyright protection tool for digital images. Perceptible watermarks safeguard the digital images in a better vigorous manner, then imperceptible watermarks. The paper presents a multiple perceptible watermarking approach for copyright protection. Two perceptible watermarks are embedded to the color digital images. The watermarked image comprehends noticeable but un-obstructive watermark evidence. The proposed system can be castoff for advertisement and copyright uses. General TermsWatermarking
