The bootloader is stored in the internal boot ROM memory (system memory) of STM32devices. It is programmed by ST during production. Its main task is to download theapplication program to the internal Flash memory through one of the available serialperipherals (USART, CAN, USB, etc.). A communication protocol is defined for each serialinterface, with a compatible command set and SequenceS
The Viterbi algorithm is the same as the binary case with one main difference: The survivor SequenceS include the uncoded bits, which are decided at each trellis stage when selecting one of two parallel branches with the largest correlation metric.
Presently, only 8-PSK modulation is considered. Extensions to higher-order modulations can be implemented following a similar procedure.
Robustnesstochangesinilluminationconditionsaswellas viewing perspectives is an important requirement formany computer vision applications. One of the key fac-ors in enhancing the robustness of dynamic scene analy-sis that of accurate and reliable means for shadow de-ection. Shadowdetectioniscriticalforcorrectobjectde-ection in image SequenceS. Many algorithms have beenproposed in the literature that deal with shadows.

SVMhmm: Learns a hidden Markov model from examples. Training examples (e.g. for part-of-speech tagging) specify the sequence of words along with the correct assignment of tags (i.e. states). The goal is to predict the tag SequenceS for new sentences.

This is a collection of m-files I created to complete a research project into the DC components of various encoding techniques. Eight of the files create random bit SequenceS that conform to their coding requirements. The others were files I found useful in the scope of the project and supplement the generating m-files.
ICA介紹課件。There has been a wide discussion about the application of Independence Component Analysis (ICA) in Signal Processing, Neural Computation and Finance, first introduced as a novel tool to separate blind sources in a mixed signal. The Basic idea of ICA is to reconstruct from observation SequenceS the hypothesized independent original SequenceS
The problem of image registration subsumes a number of problems and techniques in multiframe
image analysis, including the computation of optic flow (general pixel-based motion), stereo
correspondence, structure from motion, and feature tracking. We present a new registration
algorithm based on spline representations of the displacement field which can be specialized to
solve all of the above mentioned problems. In particular, we show how to compute local flow,
global (parametric) flow, rigid flow resulting from camera egomotion, and multiframe versions of
the above problems. Using a spline-based description of the flow removes the need for overlapping
correlation windows, and produces an explicit measure of the correlation between adjacent flow
estimates. We demonstrate our algorithm on multiframe image registration and the recovery of 3D
projective scene geometry. We also provide results on a number of standard motion SequenceS.

LiteSQL is a C++ library that integrates C++ objects tightly to relational database and thus provides an object persistence layer. LiteSQL supports SQLite3, PostgreSQL and MySQL as backends. LiteSQL creates tables, indexes and SequenceS to database and upgrades schema when needed.
