Question

the best visual compression quality is achieved using​

Answer 1

Answer:

PNG is a lossless compression algorithm, very good for images with big areas of one unique color, or with small variations of color. PNG is a better choice than JPEG for storing images that contain text, line art, or other images with sharp transitions that do not transform well into the frequency domain.

hope it helps

Answer 2

Answer:

The best visual compression quality is achieved using the wavelets.

Explanation:

• Wavelet is the new technology developed for best image compression.
• Basically wavelet is a mathematical function.
• The main advantage of using the wavelet is that it can reduce the size of the digital image to a great extent as compared to other technologies.
• But the quality of the image is not compromised in the compression process.
• Wavelet can reduce the size of image by 75% without losing the quality.
