Zero-Shot learning is a straightforward approach that can be applied to overcome this problem. A well-known problem in Deep Learning (DL) is the requirement for large amount of training data. Zero-Shot Learning (ZSL) is related to training machine learning models capable of classifying or predicting classes (labels) that are not involved in the training set (unseen classes). The introduced algorithm significantly outperforms the state-of-the-art in terms of correlation with human perceptual quality ratings. The proposed method was compared to 12 other state-of-the-art algorithms on popular and accepted benchmark datasets containing RGB images with authentic distortions (CLIVE, KonIQ-10k, and SPAQ). Among the employed local features, the statistics of popular local feature descriptors, such as SURF, FAST, BRISK, or KAZE, are proposed for NR-IQA other features are also introduced to boost the performances of local features. Specifically, we apply a broad spectrum of local and global feature vectors to characterize the variety of authentic distortions. Therefore, this paper introduces a novel no-reference image quality assessment algorithm for the objective evaluation of authentically distorted images. Since distortion-free versions of camera images in many practical, everyday applications are not available, the need for effective no-reference image quality assessment algorithms is growing. With the development of digital imaging techniques, image quality assessment methods are receiving more attention in the literature. Simulation and experimental results for different cases are presented and discussed. In this review, the performance of NLR isinvestigated for many deterministic and stochastic optical fields. Apparently, NLR seems to be a universal reconstruction method for indirect imaging. Over the years, it has been revealed that the NLR can reconstruct an object’s image modulated by an axicons, bifocal lenses and even exotic spiral diffractive elements, which generate deterministic optical fields. A new reconstruction method, termed nonlinear reconstruction (NLR), was developed in 2017 to reconstruct the object image in the case of optical-scattering modulators. In most cases, a compatible pair of the optical-modulation function and reconstruction method gives optimal performance. There have been numerous optical-modulation functions and reconstruction methods developed in the past few years for different applications. This distribution is numerically processed to reconstruct the object’s image corresponding to different spatial and spectral dimensions. The optical-recording process uses an optical modulator that transforms the light from the object into a typical intensity distribution.
Indirect-imaging methods involve at least two steps, namely optical recording and computational reconstruction.

We present a new database of phase fringe images for the evaluation of de-noising algorithms in digital holography.
In this paper, we address the question of de-noising in holographic interferometry when phase data are polluted with speckle noise. However, the phase images are corrupted by the speckle decorrelation noise. The method refers to digital holographic interferometry where the phase change between two states of the object is of interest. Digital holography is well adapted to measure any modifications related to any objects.
