Wasserstein distance, also known as EarthMover's Distance (EMD), is a metric used to measure the difference between two probability distributions. Compared with traditional KL divergence or JS divergence, Wasserstein distance takes into account the structural information between distributions and therefore exhibits better performance in many image processing tasks. By calculating the minimum transportation cost between two distributions, Wasserstein distance is able to measure the minimum amount of work required to transform one distribution into another. This metric is able to capture the geometric differences between distributions, thereby playing an important role in tasks such as image generation and style transfer. Therefore, the Wasserstein distance becomes the concept

Super-resolution image reconstruction is the process of generating high-resolution images from low-resolution images using deep learning techniques, such as convolutional neural networks (CNN) and generative adversarial networks (GAN). The goal of this method is to improve the quality and detail of images by converting low-resolution images into high-resolution images. This technology has wide applications in many fields, such as medical imaging, surveillance cameras, satellite images, etc. Through super-resolution image reconstruction, we can obtain clearer and more detailed images, which helps to more accurately analyze and identify targets and features in images. Reconstruction methods Super-resolution image reconstruction methods can generally be divided into two categories: interpolation-based methods and deep learning-based methods. 1) Interpolation-based method Super-resolution image reconstruction based on interpolation

VisionTransformer (VIT) is a Transformer-based image classification model proposed by Google. Different from traditional CNN models, VIT represents images as sequences and learns the image structure by predicting the class label of the image. To achieve this, VIT divides the input image into multiple patches and concatenates the pixels in each patch through channels and then performs linear projection to achieve the desired input dimensions. Finally, each patch is flattened into a single vector, forming the input sequence. Through Transformer's self-attention mechanism, VIT is able to capture the relationship between different patches and perform effective feature extraction and classification prediction. This serialized image representation is

The Scale Invariant Feature Transform (SIFT) algorithm is a feature extraction algorithm used in the fields of image processing and computer vision. This algorithm was proposed in 1999 to improve object recognition and matching performance in computer vision systems. The SIFT algorithm is robust and accurate and is widely used in image recognition, three-dimensional reconstruction, target detection, video tracking and other fields. It achieves scale invariance by detecting key points in multiple scale spaces and extracting local feature descriptors around the key points. The main steps of the SIFT algorithm include scale space construction, key point detection, key point positioning, direction assignment and feature descriptor generation. Through these steps, the SIFT algorithm can extract robust and unique features, thereby achieving efficient image processing.

Old photo restoration is a method of using artificial intelligence technology to repair, enhance and improve old photos. Using computer vision and machine learning algorithms, the technology can automatically identify and repair damage and flaws in old photos, making them look clearer, more natural and more realistic. The technical principles of old photo restoration mainly include the following aspects: 1. Image denoising and enhancement. When restoring old photos, they need to be denoised and enhanced first. Image processing algorithms and filters, such as mean filtering, Gaussian filtering, bilateral filtering, etc., can be used to solve noise and color spots problems, thereby improving the quality of photos. 2. Image restoration and repair In old photos, there may be some defects and damage, such as scratches, cracks, fading, etc. These problems can be solved by image restoration and repair algorithms
