An Introduction to Visual Cryptography for Binary Images Okechukwu Ikoro 7061018 INSE 6110 Abstract Visual Cryptography is a type of cryptographic scheme used to hide a secret image in shadow images called shares or layers such that it can’t be decrypted using the human visual system unless certain qualified subsets of the shares are used. The secret image is encoded without the use of any cryptographic computations. The topic of visual cryptography is a broad one with many fields however in this
Abstract—This paper involves the work done in the field of development of secure and better cryptographic algorithms for digital data like images. The paper presents a technique and its application in binary plane decomposition and two image encryption schemes. One scheme is simple and other provides high security. This proposed work achieves lossless image encryption. The paper has been carried out by dividing into five subsections: i) Introduction, ii) Literature Review iii) Proposed Methodology
REVIEW ON IMAGE PROCESSING USED IN HAEMOTOLOGY Abstract- In medical analysis blood cell count plays vital role. Variations in the count of blood cells cause many diseases in the human body. For overall health assessment and diagnosis of many disorders complete blood count is required. Abnormal increase or decrease in cell count indicates that person has indispensable medical condition. The Complete Blood Count (CBC) is a blood test, extensively used to check various disorders such as infections,
\subsection{Local Binary Pattern} Local Binary Patterns (LBP) is on of well-know descriptor used for pattern recognition \cite{G1}. LBP describes textures features of the image. It divided into two different descriptors: (1) local descriptors and (2) global descriptor. The global descriptor used for separating the non objects blocks, while the local provides detailed objects information which can be used in recognition application. It is mathematically calculated through dividing the image into blocks
wounds or soothing pain” (OED “balsam”). In a sense, “balsam” is synesthetic, as it evokes both senses of sight and smell. As a perfume, it suggests the permeating traces of femininity through scent, and as a medicinal ointment, it conjures a hopeful image that the crippling effects of patriarchy on the female body
nail in the coffin for painting, when it fact it freed it from the representational, digital has allowed analogue photography to turn away from the indexical and to examine its own materiality. We must now do the same for these ‘machine images,’ to show that an image is never just an unique perspective of an event but a process, an active, ever-changing
value in sharing moments that don't live forever.” [1] With that mindset, he was able to create Snapchat, which allows users to send images and videos to specific people. Once received, the pictures/videos can be viewed within a time frame of 1-10 seconds before completely vanishing. In addition to sharing to specific people, users are also able to share their images/videos with their friends when they post it on their “story”, which is where their contacts can then view it up to 24 hours. 2b.

weight of the lithography stones, the acid bath of etchings, and the carving of woodcuts do not allow for any other orientation. Furthermore, presses are always kept horizontal; any other orientation would not create enough pressure to transfer the image to paper. Rauschenberg’s affinity for lithography (I am suggesting) is foreshadowed in his Combines as well as in his early indexical works. In fact, it can be asserted that critical concerns like the flatbed and the index better suit his lithographs
