Processing: How can I improve the framerate in my program?

寵の児 提交于 2020-01-14 10:34:09
问题 So I've been working in Processing for a few weeks now, and, though I'm not experienced in programming, I have moved on to more complex projects. I'm programming an evolution simulator, that spawns creatures with random properties. Eventually, I'll add reproduction, but as of now the creatures just sort of float around the screen, and follow the mouse somewhat. It interacts with sound from the line in, but I commented those parts out so that it can be viewed on the canvas, it shouldn't really

How to add external libraries in processing

此生再无相见时 提交于 2020-01-14 05:56:27
问题 I have been using processing for a while and ran into an issue when I am trying to add an external java library. I followed all the steps provided online where I have to access the lib folder(processing-3.3) and add my library inside there. Unfortunately, my method did not work. Another problem I am facing is I don't know how to import this library. This is the link to the library and this is the .jar file link. Can somebody help? Regards 回答1: That library isn't wrapped as a Processing

Using JSON from Processing-JS

烈酒焚心 提交于 2020-01-13 18:25:08
问题 I want to write an application using processing-JS, and I'd like to be able to load it with server-side data. I haven't written the server side yet so I can use anything, but it seems the obvious AJAX thing would be to use JSON to upload the data into the page. How can I get access to that data from my processing code? Is it something as easy as the data is in scope, or could be attached to the window object and directly accessed from the processing code? Update : Let me refine the question a

编辑:David Doermann(马里兰大学) Karl Tombre(洛林大学) 前言 In the beginning, there was only OCR. After some false starts, OCR became a competitive commercial enterprise in the 1950’s. A decade later there were more than 50 manufacturers in the US alone. With the advent of microprocessors and inexpensive optical scanners, the price of OCR dropped from tens and hundreds of thousands of dollars to that of a bottle of wine. Software displaced the racks of electronics. By 1985 anybody could program and test their ideas on a PC, and then write a paper about it (and perhaps even patent it). 最初,只有OCR。在经历了一些错误的开始之后

语音合成概述

一、语音合成概述 语音合成,又称文语转换(Text To Speech, TTS),是一种可以将 任意输入文本 转换成 相应语音 的技术。 传统的语音合成系统通常包括 前端 和 后端 两个模块。 前端模块 主要是对输入文本进行分析,提取后端模块 所需要的语言学信息 ,对于中文合成系统而言,前端模块一般包含文本正则化、分词、词性预测、多音字消歧、韵律预测等子模块。 后端模块 根据前端分析结果,通过一定的方法生成语音波形,后端系统一般分为基于 统计参数建模 的语音合成(或称参数合成)以及基于 单元挑选 和 波形拼接 的语音合成(或称拼接合成)。 对于后端系统中的 参数合成而言 ,该方法在训练阶段对语言声学特征、时长信息进行上下文相关建模,在合成阶段通过时长模型和声学模型预测声学特征参数,对声学特征参数做后处理,最终通过声码器恢复语音波形。该方法可以在语音库相对较小的情况下,得到较为稳定的合成效果。 缺点 在于统计建模带来的声学特征参数“过平滑”问题,以及声码器对音质的损伤。 对于后端系统中的 拼接合成而言 ,训练阶段与参数合成基本相同,在合成阶段通过模型计算代价来指导单元挑选,采用动态规划算法选出最优单元序列,再对选出的单元进行能量规整和波形拼接。拼接合成直接使用真实的语音片段,可以最大限度保留语音音质; 缺点是 需要的音库一般较大,而且无法保证领域外文本的合成效果。

How to run Processing+Twitter4j sketch in broswer

北慕城南 提交于 2020-01-11 11:17:48
问题 I'm a newbie programmer practicing Processing and I recently developed a sketch that uses Twitter4j. When I run the sketch in Java mode from the Processing Development Environment it works perfectly. Also, when I export the sketch from Java mode the resulting application runs perfectly. However, when I switch to JavaScript mode and try to run the sketch the browser preview does not display anything. I believe the problem is related to Twitter4j because when I remove the Twitter4j-related code

Image processing pipeline - Part

Image processing pipeline - Part C (10%) Complete your program by implementing pipefile parsing and command-line argument parsing. Pipefile parsing (5%) Your program should be able to parse an input text file, which we can call the pipefile. The pipefile describes a complete processing pipeline using nodes in a sequence. The following pipefile, pipe1.txt , is given as an example: Your program should be able to parse any pipefile that describes nodes that you have implemented in part A. In order to parse a pipefile, you will need to implement a method that reads in a pipefile, and then creates
