The pseudo-spectral (PS) method on the basis of the Fourier transform is a numerical method for estimating derivatives. Generally, the discrete Fourier transform (DFT) is used when implementing the PS method. However, when the values on both sides of

Multichannel images, i.e., images of the same object or scene taken in different spectral bands or with different imaging modalities/settings, are common in many applications. For example, multispectral images contain several wavelength bands and hen

The goal of block matching (BM) is to locate small patches of an image that are similar to a given patch or template. This can be done either in the spatial domain or, more efficiently, in a transform domain. Full search (FS) BM is an accurate, but c

A 79-year-old man was admitted because of complete heart block. Echocardiograms showed an abnormal mass adjacent to the sinus of Valsalva. Subsequent surgical resection was not successful. Despite chemotherapy, the patient died from multiple organ fa

In this paper, we propose an efficient method for learning local image descriptors with convolutional autoencoders. We design an autoencoder architecture that yields computationally efficient extraction of patch descriptors through an intermediate im

Multispectral images contain several wavelength bands and hence have rich information. All the methods for grayscale images can be applied to multispectral images by processing each band separately. However, it requires a vast computational time, esp

We propose a gradient-based global feature and its application to seam carving. We focus on areas, rather than points and lines, to be assigned as important elements for expressing the rough location of salient objects in an image. The proposed featu

Pseudo spectral (PS) method using discrete Fourier transform (DFT) is a calculation method of obtaining the derivative in the frequency domain. When the sequence is discontinuous at its both sides, oscillatory approximation is obtained by PS method u

The goal of pattern matching is to find small parts of an image that are similar to a given template. Matching in transform-domain (such as Haar, Walsh-Hadamard, etc.) is more efficient that matching in the spatial domain. However, it has a limitatio
