编程作业二 作业链接:Seam Carving & Checklist 我的代码:SeamCarver.java 问题简介 接缝裁剪(Seam carving),是一个可以针对照片内容做正确缩放的算法(由 Shai Avidan 和 Ariel Shamir 所发表).概念上,这个算法会找出好几条 seams,而这些 seams 是在照片中最不重要的一连串像素,接着再利用这些 seams,对照片做缩放.如果是要缩小照片,则移除这些 seams,若是放大,则在这些 seams 的位置上,插入一些像…

今天首次接触了图像编辑中的seam carving知识,感觉挺神奇的.虽然我自己可能理解的不是很深刻,但是记录下来,总是好的. seam carving直接翻译过来是“线裁剪”的意思.它的主要用途是对图像进行缩放.不同于传统的按比例缩放图像的方式,seam carving的是内容感知的,它充分考虑了图像中像素的重要性,通过删除或增加seam线来实现图像尺寸的调整.它在缩放不是特别大的情况下,能够很好的保护图像中的显著物体. 具体来说,seam carving定义了穿过整幅图像的像素线(即seam…

Seam Carving DescriptionFish likes to take photo with his friends. Several days ago, he found that some pictures of him were damaged. The trouble is that there are some seams across the pictures. So he tried to repair these pictures. He scanned these…

自我总结: 1.编程的思维不够,虽然分析有哪些需要的函数,但是不能比较好的汇总整合 2.写代码能力,容易挫败感,经常有bug,很烦心,耐心不够好 题目: In this programming assignment you will implement one or more of the integer multiplication algorithms described in lecture. To get the most out of this assignment, your pro…

Programming Assignment 3: Pattern Recognition 1.题目重述 原题目:Programming Assignment 3: Pattern Recognition 题目给定n个二维平面点,搜索能够连成线的大于等于四个点的集合.需要分别实现三个类,点的类,暴力搜索,快速搜索. 点的类需要实现根据点的坐标比较以及两个点根据某个点的斜率的比较. 暴力搜索和快速搜索均需要实现寻找点的功能. 2.分析 主要是分析如何实现暴力搜索和快速搜索. 2.1 暴力搜索 这个…
