Abstract A better content based image retrieval is possible when the image pseudo hash is able to work in the wavelet transform. While decomposing the images, we identified the important wavelet detail coefficients to compose the pseudo-hash. We considered the pseudo-hashes of the images rather than the images directly to search the digital images in the large databases....

Abstract Recently the feature selection algorithms are extensively studied. Using 3D data, the features are drawn for automatic classification and identify craters. This will also help to text the performance of the classifiers. Our intention in this work is to observe the discriminative power of the original values, hereafter called “pure” values, of a minimal curvature by only converting them in the range... Recently the feature selection algorithms are extensively studied. Using 3D data, the features are drawn for automatic classification and identify craters. This will also help to text the performance of the classifiers. Our intention in this work is to observe the discriminative power of the original values, hereafter called “pure” values, of a minimal curvature by only converting them in the range of grey scale. We have tested the system and found that the five different classifiers show that better accuracy results are obtained over the features selected from the grey scale image. We also found that the method from computer vision is applied for the crater detection. Read More Read Less

Abstract In this work we have presented using a complex hadamard transform an algorithm for digital watermarking of health system images. We are able to detection the unauthorized access and attacks in the watermarking with the help of the newly introduced algorithms. The experimental results of the some attacks over the test medical images are drawn made on the base of... In this work we have presented using a complex hadamard transform an algorithm for digital watermarking of health system images. We are able to detection the unauthorized access and attacks in the watermarking with the help of the newly introduced algorithms. The experimental results of the some attacks over the test medical images are drawn made on the base of mean-squared error and signal to noise ratio of the reconstructed images. Read More Read Less
