Healthcare institution that handles a number of patients, opinions is often sought from different experts. It demands the exchange of the medical history of the patient among the experts which includes the medical images, prescriptions and electronic patient records (EPR) etc. In order to reduce the storage and transmission cost, data hiding techniques are used to embed patient information within medical images. In medical imaging applications, there are stringent constraints on image fidelity that strictly prohibit any permanent image distortion by the watermarking. Authenticity is another important aspect in medical image watermarking. To overcome the problem of occurrence of artifacts and to produce zero distorted or noise free watermarked medical images; this book presents the technique in which authors used modified difference expansion watermarking using LSB replacement in the difference of virtual border for watermarking of medical images. The Class Dependent Coding Scheme (CDCS) is used to encode the electronic patient record (EPR) data for increasing the embedding capacity. Thus providing new levels to the research in the field of medical image watermarking.

Canola is genetically improved version of rapeseed and is low in both erucic acid and glucosinolates, which distinguish it from ordinary rapeseed. As far as method of sowing is concerned, due to intensive cropping system oilseeds crops are generally sown in fields vacated by rice, cotton and potato etc. where late sowing of canola is done. Any deviation from optimum time of sowing may adversely affect growth, development differently under different environmental conditions and these conditions are subjected to change with varying date of sowing. Thus, there is need to assess the planting technology for canola and its comparison with the conventional planting technique of direct sowing of seed. Fertilizer availability and its application is another constraint in agriculture production. Nitrogen promotes vegetative growth, photosynthesis and is an important constituent of protein. Nitrogen may also affect the oil content, protein content and fatty acid profile. Nitrogen has much endurance on crop growth rate and its effect in relation to planting methods forms another aspect having a great bearing on yield.
