What are the Common Techniques Used for Lossy Compression?
Several techniques are commonly employed for lossy compression in histology:
1. JPEG Compression: One of the most widely used methods, JPEG compression applies a combination of discrete cosine transform and quantization to reduce file size. However, the degree of compression must be carefully controlled to avoid loss of critical details.
2. Wavelet Compression: This technique uses wavelet transforms to compress images more efficiently, often resulting in better retention of important features compared to JPEG.
3. Fractal Compression: Although less common, fractal compression uses mathematical algorithms to compress images. It is known for maintaining high quality at higher compression rates but is computationally intensive.
