The generation of tumor-specific T cells is hampered by the presentation of poorly immunogenic tumor-specific epitopes by the tumor. Here, we demonstrate that, although CD8+ T cells specific for the self/tumor Ag tyrosinase-related protein 2 (TRP2) are readily detected in tumor-bearing hosts, vaccination of either tumor-bearing or naive mice with an epitope derived from TRP2 fails to generate s...

Recognizing facial expressions is a major challenge and will be required in the latest fields of research such as industrial Internet Things. Currently, available methods are useful for detecting singular images, but they very hard to extract. The main aim face detection capture an image real-time search dataset. So, by using this biometric feature, one can recognize verify person’s their featu...

This paper presents a low-cost and high-quality, hardware-oriented, two-dimensional discrete cosine transform (2-D DCT) signal analyzer for image video encoders. In order to reduce memory requirement improve quality, novel Loeffler DCT based on coordinate rotation digital computer (CORDIC) technique is proposed. addition, the proposed algorithm realized by recursive CORDIC architecture instead ...

This research aims to protect Digital Elevation Model (DEM) data from piracy or counterfeiting. An invisible watermark inserted into the data, which will not considerably change value, is necessary. The proposed method involves use of two-dimensional discrete cosine transform (2D DCT), a combination 2D DCT and wavelet (DWT), Fourier DFT) in frequency domain. used include National DEM file downl...

The main goal of this paper is to embed a watermark in the speech signal, using the three techniques such as Discrete Cosine Transform (DCT) along with Singular Value Decomposition (SVD) and Discrete Wavelet Transform (DWT).In this paper, various combinations were tried for embedding the watermark image into the audio signal such as DWT and SVD, DCT with SVD and DCT, DWT with SVD. Their perform...

An individual can be identified effectively using palmprints. In this paper we propose palmprint identification based on DWT, DCT and QPCA (PIDDQ). Histogram equalization is used on palmprint to enhance contrast of an image. The DWT is applied on Histogram equalized image to generate LL, LH, HL and HH bands. The LL band is converted into DCT coefficients using DCT. QPCA is applied on DCT coeffi...

A low bit rate video coding technique that uses spatio-temporal geometric transforms is presented. Motion compensation based on the bilinear transform is employed to reduce the temporal redundancy of the video. The spatial redundancy of the motion compensated error images is reduced by a combination of Fractal and DCT. It is shown that in the objects boundaries of the motion compensated error i...

Image compression is the reduction or elimination of redundancy in data representation in order to achieve reduction in storage and communication cost. For this we use the simple computational method, 2D-DCT, using two 1D-DCT performed on matrix of (8X8). The DCT is a technique that converts a signal from spatial domain to frequency domain. Here we first convert the image into minimum code unit...
