This paper describes a novel technique to localize the OD in retinal images using the cuckoo search algorithm and the structural similarity index measure (SSIM). SSIM uses the average OD value to compare with candidate OD. Hence, the average OD values were calculated from randomly selected images...
As a result, many image processing methodologies have been recently extended to take advantage of alternative visual quality measures, the most prominent of which is the Structural Similarity Index Measure (SSIM). The superiority of the latter over Euclidean-based metrics have been demonstrated in ...
The local self-similarity descriptor is a kind of important image or video local feature description method. It is often used for detection, identification and recognition. In this paper we propose a new local self-similarity descriptor based on structural similarity (SSIM) index. It is showed in...
IQM2: new image quality measure based on steerable pyramid wavelet transform and structural similarity index In this paper, we present a new full-reference objective image quality measure—IQM2, based on structural similarity index and steerable pyramid wavelet tr... E Dumic,S Grgic,M Grgic - ...
harismuneer/Gradient-Smoothness-Structural_Similarity-Image_Histogram Star13 🖼️ This repository contains ready to run code for the following image processing techniques: Image Gradient, Image Smoothness, Image Histogram (Intensity Histogram) and Structural Similarity Index Measure (SSIM) of Two Images...
In this paper, we propose an efficient similarity index that resolves the shortcomings of the existing measures of feature and structural similarity. This measure, called the Feature-Based Structural Measure (FSM), combines the best features of the well-known SSIM (structural similarity index measure...
However, if the three components of the SSIM are integrated into the SSIM calculation, the measure index evaluates the blurred image with a high SSIM value. By contrast, a slight vertical translated image has a low SSIM score, whereas the blurred image is noisier than the translated image. ...
A structural model was developed by using target gray level image,and structural similarity index was used to measure target similarity between two frames in correlation tracking. 该方法在基于颜色直方图的粒子滤波跟踪框架中,利用目标的灰度图像建立结构模型,通过结构相似性质量因子衡量目标在两帧图像之间的相...
This paper proposes a discrete wavelet transform-based structural similarity (DWT-SSIM) method for image quality assessment. As it highlights human eyes' sensitive frequency bands, the proposed measure has a better correlation with the judgment of human observers than SSIM. Furthermore, the method ...
Finally, Structural Similarity Index Measurement (SSIM) is used to measure the similarity of palmprints and judge the palmprint category for classification. The recognition results of proposed method are stable in the PolyU palmprint database and the Blurred-PolyU palmprint database, moreover, the ...
