Description: 数字图像处理实验
根据原图像的直方图,发现背景和目标的分割值大约在130左右,并将灰度图像转为二值图像,分割效果比较理想。
图像处理实验(六)图像压缩与编码
实验目的: 学习JPEG压缩编码
实验内容:
一.实现基本JPEG的压缩和编码分三个步骤:
1. 首先通过DCT变换去除数据冗余;
2. 使用量化表对DCT系数进行量化;
3. 对量化后的系数进行Huffman编码。-digital image processing experiments based on the original image histogram, found background and objectives of the divided about the value of around 130 and two gray-scale image to image, Segmentation more satisfactory results. Image processing experiments (6) Image Compression and Coding of the experiment : Learning JPEG compression coding experiment : one. Basically JPEG compression and coding in three steps : 1. First through DCT remove data redundancy; 2. Using quantitative table right DCT coefficient quantization; 3. Right quantized coefficients of Huffman coding. Platform: |

Description: 图像分割指把图像分成各具特性的区域并提取出感兴趣目标的技术和过程,它是由图像处理到图像分析的关键步骤。小麦的图像分割是使用各种图像分割算法对小麦图像进行处理和研究,提取出有用的图像信息以实现小麦粘连籽粒的分离,为进一步利用图像处理技术分析小麦品质提供依据。因此,对小麦图像分割方法的研究具有十分重要的意义。
本文首先研究了图像分割算法的分类以及常用图像分割算法的基本原理。然后针对小麦图像的特点,研究了在不同光照、背景和连接情况下使用的小麦图像分割方法,对各种分割算法进行了比较、结合和改进。重点研究了基于小波变换的分水岭算法和阈值分割算法在小麦图像分割中的应用,并借助MATLAB工具软件对选定图像进行处理,实现了对小麦粘连籽粒的分离。最后本文对图像分割技术进行了展望。
本论文的研究对于图像分割技术在小麦品质中的应用具有一定的参考价值。
-Image segmentation is a technology and process that divide image into different character area, which is interesting us. It is a key step from image processing to image analyzing. The wheat image segmentation is a way using many algorithms does some research and processing, and it also can realize the separation of wheat adhesion and realize the extraction of useful image information. So it can lay the foundation for using image processing technologies to analysis the quality of the wheat. there is a very important meaning for the research of the image segmentation method.
This paper studies the class and the principle of segmentation algorithm in common use firstly, then, studies the wheat image segment algorithm with different illumination background. It contrasts kinds of algorithms, and improved them. This paper is based on wavelet transform, and combines with the watershed algorithm and the threshold segmentation method. Using the MATLAB software, does some process on the wheat i Platform: |

Description: Melanoma is one of the deadly diseases among skin
cancer. Melanoma detection can be done by dermatological
screening and biopsy tests which are time consuming and
expensive that requires experts from medical field. Due to cost of
dermatologist to screen every patient, an automated system is
needed for melanoma detection so that death rates can be
minimized if detected early. It can be done using various image
processing techniques. An important step in the automated
system of melanoma detection is the segmentation process which
locates the border of skin lesion in order to separate the lesion
part from background skin for further feature extraction. Platform: |
