🎨 Fixing Compressed Image Artifacts and Sky Blurring

The second paragraph delves into the limitations of the previously discussed method when dealing with compressed images from social media. It introduces a practical approach to fixing issues that the neural filters cannot resolve. The technique involves making a copy of the image, applying the 'JPEG Artifacts Removal' filter, and using a smart filter mask to restore details. The paragraph also covers the use of 'Surface Blur' to fix lines in the sky without blurring edges. A detailed process is provided, including selecting the sky, applying the blur, and using the mask to limit the effect to the sky only. The result is a visually pleasing, artifact-free image. The paragraph concludes with a reminder to utilize the JPEG artifacts removal and surface blur techniques when necessary.

Keywords

💡Low Quality Image

The term 'low quality image' refers to a digital image that has poor visual clarity, often due to low resolution or excessive compression, resulting in the presence of artifacts. In the context of the video, the low quality is characterized by the image's small file size of 29 KB and visible artifacts that detract from the image's details. The video aims to address this issue by introducing a method to improve the image quality despite the initial limitations.

💡Neural Filters

Neural filters are a class of digital image processing tools that use artificial neural networks to apply various effects or enhancements to images. In the video, neural filters are presented as a powerful feature that can help in improving the quality of low-resolution images by reducing or removing JPEG artifacts. The use of neural filters is central to the video's theme of restoring image details and reducing artifacts.

💡JPEG Artifacts

JPEG artifacts are visual distortions that can appear in images as a result of compression. These artifacts manifest as blockiness, blurriness, or pixelation and are often more noticeable in images with a lot of fine details or high contrast areas. The video discusses a method to reduce these artifacts using neural filters, which is crucial for restoring the image's original appearance.

💡Image Resolution

Image resolution refers to the dimensions of an image, typically measured in pixels. A higher resolution means more pixels and thus more detail in the image. However, the video script indicates that the issue with the image is not the resolution but the presence of artifacts due to low quality, which is related to the file size and compression rather than the number of pixels.

💡Artifact Removal

Artifact removal is the process of eliminating or reducing unwanted visual elements in an image that are not part of the original scene. In the context of the video, this refers specifically to the removal of JPEG artifacts caused by compression. The video presents a method using neural filters to achieve this, which is central to improving the image's overall appearance.

💡Smart Filter

A smart filter is a non-destructive editing feature in image editing software that allows users to apply filters to an image without permanently altering the original pixels. This provides the flexibility to adjust or remove the filter effects at any time. In the video, the user is advised to set the output to 'Smart filter' so that the strength of the JPEG artifacts removal can be adjusted later if needed.

💡Masking

Masking in image editing is the process of selectively altering or protecting parts of an image. It involves creating a layer or area within the image that can be edited independently from the rest. The video discusses using a mask to selectively apply different strengths of the 'JPEG artifacts removal' to different areas of the image, allowing for more precise control over the editing process.

💡Surface Blur

Surface blur is a type of image blur effect that selectively blurs areas of an image while preserving edges and details. Unlike a standard blur, which smooths the entire image, surface blur allows for a more controlled blurring effect that can help in fixing specific issues without losing the sharpness of the image's details. In the video, surface blur is used to address areas where the 'JPEG artifacts removal' did not fully fix the issues.

💡Layer Duplication

Layer duplication in image editing involves creating an exact copy of an existing layer. This allows for non-destructive editing, as changes can be made to the duplicate layer without affecting the original. In the video, the user is shown how to duplicate layers to apply different strengths of the 'JPEG artifacts removal' to various parts of the image, providing a more tailored editing approach.

💡Image Compression

Image compression reduces the file size of an image by minimizing the amount of data it contains. This can be achieved through various algorithms that remove redundant or less important information. However, excessive compression can lead to a loss of image quality and the introduction of artifacts. The video addresses the common issue of image compression, particularly in the context of sharing images on social media, which often involves significant compression.

💡Non-Destructive Editing

Non-destructive editing refers to techniques in image editing where changes are made in a way that the original image data remains unaltered. This allows for flexibility to revert or modify the edits without losing the original quality. In the video, the use of smart filters and masks exemplifies non-destructive editing, as these allow the user to adjust or remove effects without permanently changing the image.
