The resolution of an image refers to the number of pixels an image contains. Higher-resolution images are those images with a maximum number of pixels. A higher-resolution image is a high-quality image. But there are some images that come with low pixels and hence low resolution. There are many ways to increase image resolution, such as OCR API. So you will learn about how to increase the resolution of an image in this blog post.
Knowing the names and ways is not the only things needed to increase image resolution. We need to observe the features, pros, and cons of each application, such as OCR API, so we can use them according to our requirements. This article is a complete guide on how to increase the resolution of an image or upscale image. Let’s continue reading!
Can You Enhance The Quality Of A Low-Resolution Image?
Yes, it is possible to enhance the quality of low-resolution images. We can achieve it by knowing how to increase resolution of images.
However, increasing the resolution sometimes affects the visual quality of the resized image.
But there are some software programs, such as:
- Adobe Photoshop
- Photo Enhancer
- Image Upscaler
- GIMP
- ON1 Size
What Is Resampling An Image?
As we know, we need to change the resolution to make a high-quality image. We have to add pixels or subtract pixel dimensions to improve the quality.
The process of modifying pixels per inch in an image is known as resampling.
If we decrease the number of pixels in an image, it refers to a process known as downsampling.
On the other hand, increasing the number of pixels refers to upsampling.
Downsampling is often performed to decrease image size to save storage space. While upsampling is known as a complicated process.
How Does Resampling Affect Resolution?
It is a fact that we don’t want to make guesses with images that are important to us.
Therefore, we take help from machine learning and artificial intelligence. It will help perform resampling and increase image resolution without affecting quality.
Resampling is adding the best-looking pixels to our images according to the context of the images.
Google Photos developers also use artificial intelligence to improve their photos.
How To Increase the Resolution Of An Image?
We can increase image resolution through multiple software programs. Adobe Photoshop is one of those programs to increase image resolution.
When improving the resolution of an image, we need to follow the given steps:
- Increase image size to ensure an optimal pixel density.
- Avoid a large increase in size, as it will reduce the sharpness of your images.
- Use sharpening tools to increase the sharpness of images.
