The Fourier Transform Profilometry method in MATLAB is based on the analysis of a reference grating and a deformed grating to obtain the folded phase. After phase unwrapping, the height information of the object is derived based on the relationship between phase and height.

在自然语言处理（NLP）领域，情感分析是一项重要任务，涉及对文本进行分析，提取其中的情感色彩，如正面、负面或中性情绪。本项目名为“根据情感词进行分析《文本情感分析代码》”，其核心目标是利用特定的算法和技术来进行分词和分句处理，并对词汇和句子进行情感评分。分词是情感分析的第一步，依赖于词典和统计模型，如jieba分词库、HMM和CRF等机器学习方法。分句使用NLTK中的PunktSentenceTokenizer和结巴分词的句子切分功能。情感词典如SentiWordNet、AFINN和SnowNLP用于快速打分，计算情感词的频率和情感强度。情感评分基于词典匹配和词权重加权求和，利用词向量和预训练模型捕获语境含义，提高评分准确性。情感极性判断可能涉及SVM、朴素贝叶斯、CNN和LSTM等算法，实现对情感强度和方向的分类。
