Process-based Mapping Using Spectral Indicators in an Image Template Matching Approach
In geologic imaging spectroscopy studies, typical end products are often mineral maps. These maps are usually ambiguous and form a limited method of representing geological information that is potentially contained in spectroscopic images. This situation can be improved by mapping the spatial configuration of the effects of geological processes instead of the solely individual minerals in a non...
متن کاملTemplate Matching Approach on out of focus Blurred images using Iterative Wiener Filter and Neural Network
Barcode technology plays an important part in people’s daily lives. Out-of-focus image blur are not handled properly by most modern devices which is based on barcode scanning technologies. In existing system, spatial domain template matching approach is used. This works entirely on spatial domain which is capable of reading linear barcodes from low-resolution images containing severe Out-of-Foc...
متن کاملApplications to Pattern Matching Using Spectral Theory and Its Performance
コンピュータビジョンにおいて画像の中から特定の パターンを探し出すパターンマッチングは基本的な処 理である.パターンマッチングには,2枚の画像の相関 値に基づく相関テンプレートマッチングや,画像の代 表的な特徴点同士を照合する特徴点マッチング [1], [2] が知られる. 相関テンプレートマッチングにおいては,対象物の 回転やスケール変化等に対応するために,姿勢の異な る複数のテンプレート画像を何度も照合を行う.一方 で,顔認証などでは多数のテンプレート画像を主成分 分析により圧縮して照合を行う固有顔法や,同様の考 えに基づく固有空間法が知られている [3]~[6].また, 近年では多数の画像を有限区間の直交多項式で近似す る方法も提案されている [7].このように多数枚の画像 を圧縮・近似して,テンプレートマッチングへ応用す ることは常套手段となっている. 一方で,SIFT (S...
متن کاملColor Image Registration and Template Matching Using Quaternion Phase Correlation
Due to mathematical limitations, conventional phase correlation technique can only be applied to grayscale images or at most complex images. A full colour image must be first converted to a grayscale image before performing the phase correlation, during which the luminance information has been wasted. In this paper, an extension of the phase correlation technique to the quaternion field , based...
متن کاملImage Tracking Algorithm using Template Matching and PSNF-m
The template matching method is used as a simple method to track objects or patterns that we want to search for in the input image data from image sensors. It recognizes a segment with the highest correlation as a target. The concept of this method is similar to that of SNF (Strongest Neighbor Filter) that regards the measurement with the highest signal intensity as target-originated among othe...
