Gabor Filter in Edge Detection is a technique for improving image edge detection. Previously in our articles, we explored a simple technique for edge detection using OpenCV – Canny Edge…Continue readingGabor Filter in Edge Detection
Canny Edge Detection is a method to identify edges of objects within an image. Consequently today we would like to introduce how you can apply this technique using OpenCV and…Continue readingCanny Edge Detection
Previously we talked about how to improve the contrast of a grey scale image. Subsequently we looked at how we could apply similar techniques on color images [INSERT LINK]. During…Continue readingColor Image Histogram CLAHE
In our earlier post, we talked about how the histogram of a black and white picture enabled us to understand the pixel intensity distribution. Furthermore, by equalizing its’ histogram we…Continue readingColor Image Histograms
Image Histograms and Contrast Today we will be talking about image histograms and contrast. In the past, we’ve talked about how to generate Histograms and visualizations in Python. Subsequently, we…Continue readingImage Histograms and Contrast
Contours and Hierarchy When there are many contours or shapes detected in an image, finding which shape to draw the bounding box around can get tricky. Especially in cases when…Continue readingContours and Hierarchy
Contours and Bounding Boxes More often than not, the images we take consist of a complex composition. Particularly, it may contain one or more objects of interest. If we wanted…Continue readingContours and Bounding Boxes
Image Thresholding As the name implies, image thresholding allows us to apply a certain “threshold” to determine whether each pixel is of interest to us or not. Consequently, there are…Continue readingImage Thresholding
Color Space Color is a human perception and describes the visible spectrum of light that is reflected off the surface of any object. With the advancement of computers, we went…Continue readingColor Space
Skews and Perspectives Is that a car or is that a bike? The key is which end are you looking at it. Today we introduce the topic “Skews and Perspectives”…Continue readingSkews and Perspectives
