Subpixel Computer Vision Detection Based on Wavelet Transform

Abstract

Computer vision detection technology is one of the most popular topics in the field of computer vision. With the continuous improvement of the relevant algorithm and the performance-price ratio of the corresponding imaging equipment, the corresponding computer vision detection algorithm is also constantly upgraded and deepened. Computer vision detection technology is mainly used in transportation, public security, national defense and military fields, but the pixel accuracy of traditional computer vision detection technology has been unable to meet today's accuracy requirements. In this paper, firstly, the quantum denoising algorithm based on dual-tree and dual-density wavelet transform is used to realize the combination of quantum image coding expression and wavelet transform, and finally achieve a more detailed and accurate description of the image and realize the noise reduction of the image. In order to further realize sub-pixel image processing, cubic spline interpolation edge detection algorithm will be added to wavelet transform, which mainly calculates the zeros of the second-order function corresponding to the cubic spline function on both sides of the image edge points, so as to realize sub-pixel location of the image edge points. Finally, by comparing with the traditional pixel accuracy detection algorithms, it can be found that the proposed subpixel computer vision detection algorithm based on wavelet transform has good robustness, and its computing time is relatively faster, so it will have better adaptability in practical applications.

Implementasi Metode CNN Computer Vision Dalam Identifikasi Tipe Kerusakan Pohon Berbasis FHM

“…Penerapannya metode ini sulit pada hutan tropika, dan membutuhkan banyak sumber daya manusia untuk mendapatkan data status keakuratan yang tinggi. Permasalahan tersebut dapat dipecahkan oleh metode computer vision dimana dalam mendapatkan tingkat keakuratan yang tinggi tidak diperlukan sumber daya manusia yang banyak, melainkan karakteristik data akan menentukan data status keakuratan dalam penelitian, selain itu computer vision sebagai bagian teknologi dalam pendeteksian memiliki beberapa karakteristik penting yang diantaranya adalah presisi nya yang tinggi [6].…”

Two Advanced Models of the Function of MRT Public Transportation in Taipei

“…The purpose of this step was to screen the input variables with a lower correlation to the Taipei MRT passenger traffic to avoid interfering with the prediction results. The regression analysis is primarily used to discuss the causal result relationship among the variables and conduct the prediction via a line chart [20,21], a scatter chart [22], correlation analysis [23][24][25], the enter method [26,27], and stepwise regression [28][29][30].…”
