STEGANALYSIS ALGORITHM FOR PNG IMAGES BASED ON FUZZY LOGIC TECHNIQUE

5 shows input image and resultant encrypted images for different mapping images using proposed selective encryption based on sub-blocks.. From these resultant images we can

Key words: Cancer detection, speckle noise, fuzzy logic, ultrasound images, imaging techniques,.. image quality,

In the proposed algorithm, first the neural Network is trained to reject the non-eye regionbased on images with features of eyes and the images with features of non-eye using

characteristics, and, for this, based on fuzzy logic, the present study uses the fuzzy c-means method to cluster Iguaçu river floods, observed in União da Vitória, using a set of

The features of the images were extracted, and passed into training using principal component analysis, while another set of 50 images were used for testing. The same

In this sense, the Middle Ages is one of the historical periods in which the body has played a decisive role as an agent motivating the appearance of images- object in the context

By introducing the trust scheme into the fuzzy logic scheme to represent the reliability of the nodes, a cooperative spectrum sensing scheme based on trust and fuzzy logic for

In this work, we carried out feature extraction using modified view based approach of original and thinned images and sub images of original and thinned images for
