Lossless Image Compression
Compression Beyond FAQ
Gigabit Ethernet (GigE) is the most widely used interface in industrial vision applications, thanks to its long cable length, low cost, and easy integration with GigE Vision standards. 5GigE and 10GigE are established interfaces designed to enable the next generation of computer vision applications. However, if your application is not ready for five or even ten times the speed of standard Gigabit Ethernet, you can still remove bottlenecks in your existing Gigabit Ethernet setup using Compression Beyond. It is available on Basler ace 2 PRO models. You can get all your questions answered here.
Download FAQs1. What is Compression Beyond?
Compression beyond is a powerful in-camera feature developed by Basler to break through GigE bandwidth limits. You can enable the feature through pylon Viewer.
2. What are the possible scenarios to benefit from Compression Beyond?
Compression Beyond feature gives you extra bandwidth beyond the nominal bandwidth capacity of GigE Vision --without requiring extra efforts.
3. How does Compression Beyond work?
The basic principle of lossless compression of image data is based on the use of redundancies. Images that contain many redundancies are more compressible.
4. How much more bandwidth can I expect to obtain?
With Compression beyond feature, frame rates increase in the range of 2 to 3 times become reality- Depending on the respective image content.
5. Does Compression Beyond affect my image quality?
No. Image quality will be maintained in full when you choose lossless compression. In the meantime, lossy compression is still available for you to find the optimal balance between image size and image quality.
6. Does Compression Beyond affect CPU load?
Yes, but minimal for many cases. The following comparison table shows that memory loading is barely affected and the cost on CPU loading is only 3% more in lossless compression.
Test camera: ace 2 PRO GigE camera (a2A5328-4gmPRO)
Compression Beyond Feature | Compression Rate | FPS | Bandwidth | CPU Loading | Memory Loading |
|---|---|---|---|---|---|
OFF | N/A | 4.2 | 102.8 | 17-34% | 48% |
ON: Lossless Compression | Lossless 70 | 6 | 36.7 | 28-37% | 49% |
ON: Lossy Compression | Fixed Ratio 50 | 4.8 | 51.5 | 36-48% | 48% |
7. How reliable is Compression Beyond? It is just as reliable as any Basler GigE or USB 3.0 cameras. Compression beyond feature does not sacrifice the reliability of image data transfer in any way. Our standard deviations test on different vision tasks shows the high reliability of the image results.
Standard deviation test results based on 100 test images/mode.
Compression Beyond Feature | Compression Rate | Pattern X | Pattern Y |
|---|---|---|---|
OFF | N/A | 0.011 | 0.01 |
ON: Lossless Compression | Lossless 70 | 0.012 | 0.023 |
ON: Lossy Compression | Fixed Ratio 50 | 0.009 | 0.015 |
Standard Deviation Max - Min | 0.003 | 0.013 |
8. Which models are Compression Beyond available with?
Compression Beyond, together with some other powerful Basler unique features are available on all ace 2 PRO models.
9. Which one should I choose: 1GigE vs. 1GigE+Compression Beyond vs 5GigE?
There is no perfect solution without compromise; finding the right solution is always about finding the balance between cost, quality, and time that best fits your needs. Download our FAQ to learn about the advantages and compromises of each option.
