To Do List

• The Kernel in the Guided Image Filter.
  Try again using the equations in Guided Image Filtering.
• AR Model Estimation Using LMS.
• System Identification with a Limited Bandwidth Input Signal and Region of Interest.
  Try to come up with regularization (Maybe in the frequency domain?) to solve this.
• Estimate Instantaneous Frequency Using LMS Algorithm.
  Check if it works for really low frequencies.
• Sequential Form of the Least Squares Estimator for Linear Least Squares Model.
  Add derivation for the case of Forgetting Sequential LS and for Weighted Sequential LS. Probably better done in different questions.
• Feature Extraction for Image Classification of Vegetables and Fruits Using Classic Computer Vision Techniques.
  Create a simple example using MATLAB and some feature extractor.
• What is the relationship between beamforming and Independent Component Analysis (ICA).
• Image Processing Pipeline for Segmenting Cell Nuclei.
• Which Discrete Non Linear, Time Invariant Systems with Memory are Considered "Easy" to Model and Identify.
• How to Calculate Gaussian Kernel for a Small Support Size
  Suggest doing it in Frequency Domain with a direct calculation on the frequency domain of the kernel.
  Related to Constructing a Gaussian Kernel in the Frequency Domain, Is the Discrete Gaussian Kernel an Eigenfunction of the DFT and A Survey of Gaussian Convolution Algorithms.
• Unscented Kalman Filter for Tracking Amplitude, Frequency and Phase of a Multi Component Signal.
• ds
