High Resolution and Image Compression Using the Discrete Cosine Transform
The information gathering capacity of the visual system can be specified in units of bits/mm2. The fall-off in sensitivity of the human visual system at high spatial frequencies allows a reduction in the bits/mm2 needed to specify an image. A variety of compression schemes attempt to achieve a further reduction in the number of bit/mm2 while maintaining perceptual losslessness. This paper makes...
متن کاملJPEG Encoder using Discrete Cosine Transform & Inverse Discrete Cosine Transform
In the past decade, the advancement in data communications was significant during explosive growth of the Internet, which led to the demand for using multimedia in portable devices. Video and Audio data streams require a huge amount of bandwidth to be transferred in an uncompressed form. The objective of this paper is to minimize the number of bits required to represent an image and also the ac...
متن کاملImage Compression Using Discrete Wavelet Transform And Discrete Cosine Transform
The area of digital image processing has witness a great deal of development during the past few decades. Image compression is one of most important aspects of the fields. The paper presents simple and efficient algorithm for compressing image data, the algorithm involved using the glory wavelet transform technique, which was the most usable method for varied image processing field due to its r...
متن کاملImage Compression Using Discrete Cosine Transform & Discrete Wavelet Transform
Image compression plays a vital role in digital image processing. The need for image compression becomes apparent when number of bits per image are computed resulting from typical sampling rates and. quantization methods. For example, the amount of storage required for given images is (i) a low resolution, TV quality, color video image which has 512 x 512 pixels/color,8 bits/pixel, and 3 colors...
متن کاملHigh Security Multiple-image Encryption using Discrete Cosine Transform and Discrete Multiple-Parameter Fractional Fourier Transform
—A multiple-image encryption scheme is proposed by using discrete cosine transform and discrete multiple-parameter fractional Fourier transform (DMPFRFT). Each image is performed by discrete cosine transform and filtering procedure and then multiplexed into a complex signal. After operated by a pixel scrambling, the complex signal is multiplied by random phase mask, and then encrypted into one...
