Under the same experimental conditions, the test results using the aggregation operation method perform better in both PSNR and SSIM values. Inspired by this trend, some scholars proposed to use the computing power of convolutional neural networks to calculate the parameters that need to be estimated in the physical imaging model [, The emergence of the GAN (generative adversarial network) opened up another path for image enhancement issues. Element interactivity and intrinsic, extraneous, and germane cognitive load. For example, if youre driving on the freeway and you notice cars bunching together in the left lane down the road, you might decide to change into the right lane. It then connects each decomposed problem to establish a complete solution. Using UICM (color measurement index), UISM (sharpness measurement index), UIConM (contrast measurement index) as the evaluation basis. Hambarde, P.; Murala, S.; Dhall, A. UW-GAN: Single-image depth estimation and image enhancement for underwater images. A theoretical exploration of cognitive load to guide the teaching of computer programming by tailoring the use of different programming language types (visual vs textual) to the developmental needs of students relative to the complexity of the cognitive concepts being taught so that the cogitative processing capacity of students is not exceeded. Working memory differs from long-term memory in . Data are the raw facts or observations of nature and computation is the manipulation of data by some systematic procedure carried out by some computing agent. To further verify the generalization ability of FE-GAN, we selected 990 images from the artificially synthesized dataset for testing and compared them with the corresponding ground truth images. UIQM expresses as follows: In the ImageNet dataset, we randomly selected 5500 pairs of images for training and the remaining 628 pairs for testing. Computational thinking is a problem-solving skill that develops an algorithm, or series of steps to perform a task or solve a problem. This process occurs through filtering out irrelevant information and identifying whats most important. Seeing is understanding: The effect of visualisation in understanding programming concepts. In driving, we use pattern recognition to predict and respond to different traffic patterns processes. Please note, this is not a comprehensive listing but is representative. Even if a computational solution cannot be repeated in whole for a different problem or goal, pattern recognition can help identify parts of different problems that may be resolved using pieces of other solutions. interesting to readers, or important in the respective research area. All rights reserved. This paper proposes a fast and efficient underwater image enhancement model based on conditional GAN with good generalization ability using aggregation strategies and concatenate operations to take full advantage of the limited hierarchical features. These heuristics for computational thinking are very similar to the heuristics usually given for the 5-step scientific method taught in grade school, which is often written out as something like: These are nice guidelines but theyre not mandatory. Introduction. To quantitatively analyze the enhancement effect of the FE-GAN model on the paired underwater image, we choose PSNR (peak signal-to-noise ratio) and SSIM (structural similarity) as reference indicators. For example, if youre faced with writing a large, complex paper, you might choose to tackle it by decomposing the paper into smaller sub-sections and tackling each of those separately. In addition, being able to identify the general principles that underly the patterns weve identified allows us to generalize patterns and trends into rules. This helps the system storage by decreasing file size and also utilizes routines that are more efficient in processing. The latest iteration of Google Drive call Drive File Streaming is a prime example of how this can be applied to our entire datastore. This helps the programmer to save time reinventing the wheel when a solution to a given problem may already exist. Through the learning of paired images, FE-GAN achieved end-to-end underwater image enhancement, which effectively improved the image quality. Usually, red light with the longest wavelength is absorbed the fastest, and the propagation distance is the shortest. Nevertheless, our model does not perform well in enhancing darker images, especially in recovering details and textures, which means that it is still challenging in deeper waters, where artificial light sources are needed.
