SIGMA DELTA QUANTIZATION FOR IMAGES

VAlue proposition

The value proposition of this technology lies in its innovative approach to image quantization using Sigma Delta quantization. By segmenting pixel values into columns and quantizing each column as a whole using Sigma Delta modulation, the technique minimizes accumulated quantization error, thereby enhancing the reconstruction quality of the image. Furthermore, the 2D generalization of Sigma Delta modulation allows for a more comprehensive quantization process. This technology not only improves the efficiency of digital signal processing by reducing the information conversion rate but also ensures the reconstruction quality is maintained. Its practicality is further enhanced by the ability to operate in an online manner, making it suitable for real-time applications. The simplicity of the mathematical operations involved, particularly the preference for addition and subtraction over multiplication and division, makes it feasible for implementation in analog hardware.

 

Description of Technology

This technology introduces a novel method for image quantization through the application of Sigma Delta quantization. By segmenting pixel values into columns and quantizing each column as a whole using Sigma Delta modulation, the technique effectively minimizes accumulated quantization error, thereby enhancing the overall reconstruction quality of the image. The 2D generalization of Sigma Delta modulation further refines this process, allowing for a more comprehensive quantization approach. This method not only improves the efficiency of digital signal processing by reducing the information conversion rate but also ensures that the reconstruction quality is maintained. Its practicality is further enhanced by the ability to operate in an online manner, making it suitable for real-time applications. The simplicity of the mathematical operations involved, particularly the preference for addition and subtraction over multiplication and division, makes it feasible for implementation in analog hardware.
