    Application of graphics Backgrounds A good background should have a consistent colour scheme which is eye-catching without being overpowering to your eyes. So depending on the style of site should use block colours this will give the website a sleek but simple look. But depending on the purpose of a site the background colours etc. can vary e.g. if a background was for a childrens sight it may be colourful or a car site may be a steely grey if it was intended to sell sports cars e.g. an Aston Martin

    In today’s world when whole world become digitized there is need not only to store and transmit data but security is also main concern i.e. transmission of data with high security. In earlier time there ware attempts to hide a message in trusted media so as to deliver it across the enemy territory[1]. In the modern time of digital communication, several methods are used for hiding information in any medium. There are many method one of such technique is steganography[2] in which digital images are

    will show print screens of different types of compression techniques, megapixels under image quality & resolution and three different types of colour depths. I will explain the reasons why some are larger compared to others. The format includes PSD, JPEG, TIFF, BMP and GIF. I will also go into detail why colour depths will affect the quality of the final output that the file has created. File formats: As you know, there are 5

    Abstract— This paper presents the design of an optimized Compressive Sensing (CS) based image compression technique for data transmission over mobile wireless noisy channel. The proposed technique is more robust to channel noise. It uses individual measurement driven coding scheme, which facilitates simpler encoder design. The shift of computational burden from encoder to decoder is more suitable for mobile devices applications where computational power and battery life are limited. This paper also

    increased in size the image then becomes pixelated, this means that the image will loses quality. The files size for a 200x200 image will always be 118 Kb. A bitmap is usually use for photos that you have taken on a digital camera which are for example JPEG files(13). Lossless Lossless is a type of compression, when the file is compressed the quality still stays the same when the file is reloaded and all the information will be restored completely. This method of compressing files can be applied to

    Introduction In order to fulfil the task presented, which was to create an android app which displays a university campus map – with clickable buildings showing the available computers in the building while also having buttons for reserving a computer. In addition to being able to cancel a reservation, and alter the number of computers available dependant on reserving or cancelling reservations. To do this I have to plan the procedure I will take while coding it using the AppInventor program. First

    block is also a (8×8) block composed of P(m,n). As a result of transformation, the element in the upper most left corresponding to zero frequency in both directions is the DC coefficient and the rest are called as AC coefficients. QUANTIZATION IN JPEG Quantization is a lossy step where we loose data. The DCT is a lossless procedure , the data undergoing through this procedure can be precisely recovered through the IDCT . During Quantization every coefficients in the (8×8) DCT matrix is
