2017-08-20 11:28:17 -0500 asked a question Question about resizing and cropping https://snag.gy/DOdZBc.jpg First: I have an image that I want to adjust the resolution of to a set resolution with a desired scale to ratio around the head.. currently i have this going widthO, heightO = image.shape[:2] ## original width and height image = cv2.resize(image,(2170, 2894), interpolation = cv2.INTER_AREA) new_dimensionX = heightO * 631 / ((pointOfEight) - (pointOfInterestX)) new_dimensionY = widthO * 631 / ((pointOfEight) - (pointOfInterestX )) image = cv2.resize(image,(int(new_dimensionX), int(new_dimensionY))  I need the head to be with the height of 631. I'd like to maintain the 2170,2894 size on the last calculation. Any help? Also, on that note. Once that occurs, I can calculate those three dots. And I want to center the image based on the middle dot such that the nose will have a straight line going vertically through it at the center. This is my attempt: Rx = new_dimensionX / heightO Ry = new_dimensionY / widthO crop_img = crop_img[0:2894, int((pointOfNose - 2170/2) * Ry):int(pointOfNose + 2170/2 * Ry)]  2017-08-16 03:48:44 -0500 asked a question Snap to grid cropping This may be called "Region of Interest" I'm not exactly sure. But, what I'd like to do is rather easy to explain. I have a photo that I need to align to a grid. https://snag.gy/YaAWdg.jpg For starters; the little text that says "here" must be 151px from the top of the screen. Next; from "here" to position 8 of the chin must be 631px Finally; a straight line down the middle of the picture at line 28 on the nose must be done. If i'm not making sense please tell me to elaborate. I have the following ideas (this is pseudo code) It is simply to loop until the requirements are met with a resize function, a lot like brute forcing but thats all i can think of.. i.e.. while (top.x,y = 151,0) img.top-=1 ## this puts the image one pixel above until reaching the desired positioning while (top.x,y & eight.x,y != 631) resize += 1 # resize by 1 pixel until the height is reached ## center the nose image.position = nose.  2017-08-16 02:36:46 -0500 asked a question Please help me with HEAD cascades I need to find the entire head, not just the face. I found one cascade for head + shoulders, doesn't work too well.. 2017-08-16 01:41:11 -0500 asked a question OpenCV and CR2 Files. Woah I need help with this one. I can't get PythonMagick working because it is no longer supported. I can't use DCRaw because its too confusing. I can't use raw kit because it doesn't work well. What can I do to open a CR2 file with OpenCV?! 2017-08-12 12:15:31 -0500 asked a question Free Transform / Image Resize Image resize does not maintain the photo quality when used. Photoshop has a Free Transform feature, I want something similar. Does it exist in OpenCV? 2017-08-12 10:56:30 -0500 asked a question detect chin I've come far enough to be able to detect the top of a head with its hair and the chin in this method. I'm writing a program to process images in a specific format so the head will always be easy to detect. The chin is usually 8. I need an accurate way of calculating what # the chin is!

I'm coding on macOS. If someone can show me some working examples for head detection on macOS please do so. 2017-02-12 11:56:49 -0500 asked a question Cannot run... package com.example.qwill.opencvtests; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.support.v4.content.res.ResourcesCompat; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import org.opencv.android.BaseLoaderCallback; import org.opencv.android.LoaderCallbackInterface; import org.opencv.android.OpenCVLoader; import org.opencv.core.Core; import org.opencv.core.KeyPoint; import org.opencv.core.Mat; import org.opencv.core.MatOfDMatch; import org.opencv.core.MatOfKeyPoint; import org.opencv.features2d.DescriptorMatcher; import org.opencv.features2d.Feature2D; import org.opencv.features2d.FeatureDetector; import org.opencv.features2d.Features2d; import org.opencv.photo.Photo; import org.opencv.imgcodecs.Imgcodecs; import org.opencv.utils.Converters; import org.opencv.android.Utils; import java.io.File; import java.util.Vector; public class MainActivity extends AppCompatActivity { FeatureDetector test; private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) { @Override public void onManagerConnected(int status) { switch (status) { case LoaderCallbackInterface.SUCCESS: //opencv is loaded! { test = FeatureDetector.create(FeatureDetector.FAST); //feature detector goes here!
