Abstract

Data compression technology is the process of converting a set of data into a lower coded representation of data that is not encoded with a certain encoding. Data compression is done by encoding each character into a shorter coded message, in order to save storage space requirements and time for data transmission. Compressing is used to speed up the sending process from uncoded characters to certain encoded characters. By compressing, large data will be reduced in size so as to save storage capacity. In this study, using the Prefix Code algorithm, by using this method the compression results are very good in making data transmission and transferring video file allocations easier and faster. By doing compression, large data will be reduced in size so that it can save storage space. There are many types of methods or algorithms in video file compression, but in this algorithm the writer only wants to know the compression process using the Prefix Code algorithm using the C1 code where the author has successfully compressed a video file with the prefix code algorithm using the C1 code has the ability to compress video file 37, 5% on a video file.Keywords: Compression, Video, File, Prefix Code, Algorithm.

Abstract

A Digital Image may have important information in it where this confidential information should not be seen by unauthorized people. Information in a digital image can be easily remembered by others compared to information in the form of text. For this reason, images containing information must be encrypted using cryptography, but encoding the image is of course not enough to protect the information contained in it because the key may be known by outsiders.To maintain the confidentiality of information from digital images, digital images will be encoded using the IDEA algorithm, but the level of security of the algorithm should be improved. Therefore, to improve the quality of digital image security, the IDEA algorithm key is first modified using a Multiplicative Random Number Generator.Through the IDEA algorithm process which is quite complicated, coupled with the previously modified key using the Multiplicative Random Number Generator, it is hoped that it can improve the quality of the security of confidential information encoded in a digital image, so that the information contained in the digital image does not leak to it. irresponsible party.Keywords: Digital Image, Modification, Cryptography, IDEA, Multiplicative Random Number Generator.

Abstract

The era of technology that is increasingly developing nowadays has an influence on knowledge, one of which is the introduction or identification. The identifier is a stage in the development of an identification system with image processing and detection. In the introduction of fruit seeds, there are some people or lay people who find it difficult to distinguish the types of fruit based on the seeds of the fruit because there are several fruits that have seeds that are almost the same shape and color, so there may be errors in determining the type of fruit. To find out the type of fruit based on the seeds, he identified the seeds. This identification is done to classify in order to know the results of these types of fruit by applying the Viola Jones method which can help in identifying because the Viola Jones method is an algorithm that can detect objects in the image. In this method there are several concepts that are combined into a method so that it can detect and detect an object of the seed made. The Viola Jones method uses the Haar feature as a descriptor, then combines Integral Image and AdaBoost to find and select values and objects and form a Cascade Classifier that will be used as a detector. This identifier is useful for the community to be able to recognize or know the type of fruit through the seeds.Keywords: Image, Contraharmonic Mean Filter, Noise Reduction.

Abstract

Image modification is the process of manipulating part or all of the image area with the help of digital image processing techniques. Image fakes are generally difficult to analyze with the naked eye because the resulting image from the image modification process is difficult to distinguish with the naked eye. The ease of creating and changing an image can damage the credibility of the authenticity of the image in various aspects, thus making it prone to be used for criminal acts because image changes in digital images can change the information conveyed to be different. This is the basis of this research to detect the authenticity of an image. The Grostl method is a hash function to detect changes in digital images, the Grostl hash function is used to determine whether an image has been modified or not. The application of the Grostl method to generate a hash code from a digital image begins by inputting the digital image as the object to be hashed.Keywords: Image Originality, Hash, Grostl

Abstract

The size of the application file is sometimes relatively large, where the better the quality of the application file, the larger the file size needed to store the application file. With a very large application file size, during the transfer process, the transfer process may fail because the media storage space exceeds the limit. The solution to this problem is that the application files can be compressed in order to speed up transferring and storing application files. Compression of application files can be done by reducing the size of the application files by reducing the bits in the application files, but not eliminating or creating corrupted application files. By compressing, large data will be reduced in size so as to save storage space. In this study, the algorithm used is Punctured Elias Code, by using this algorithm, the compression results of the values have different results for each value, and the compression results will make sending and moving application files easier.Keywords: Compression, Files, Hadith Applications, Algortima Punctured Elias Code.
