python - Is it possible to get color gradients under curve in matplotlib? -

-
Image
i happened see beautiful graphs on page shown below: is possible such color gradients in matplotlib? there have been handful of previous answers similar questions (e.g. https://stackoverflow.com/a/22081678/325565 ), recommend sub-optimal approach. most of previous answers recommend plotting white polygon on pcolormesh fill. less ideal 2 reasons: the background of axes can't transparent, there's filled polygon overlying it pcolormesh slow draw , isn't smoothly interpolated. it's touch more work, there's method draws faster , gives better visual result: set clip path of image plotted imshow . as example: import numpy np import matplotlib.pyplot plt import matplotlib.colors mcolors matplotlib.patches import polygon np.random.seed(1977) def main(): _ in range(5): gradient_fill(*generate_data(100)) plt.show() def generate_data(num): x = np.linspace(0, 100, num) y = np.random.normal(0, 1, num).cumsum() retur

opencv - Canny Edge vs Thresholding for contour estimation in Open CV -

-
i using open cv image processing application involves contour estimation in images. know whether thresholding image (like how have done here ) or using canny edge algorithm ( here ) yields better result. involve algorithmic analysis or missing something? canny edge detection obviously. whole bunch of things ensure strong edges come out of result. thresholding takes @ intensities , sees whether or not each value smaller or larger , "edge" points respectively. however , depending on complexity of scene, thresholding , edge detection yield same thing. example, if had clean image multiple crisp objects have clear intensity difference between foreground , background, either edge detection or thresholding work. if had more complex image contrast different in different areas, or if had multiple objects different intensities, thresholding not give results because inevitably including in pixels don't belong proper objects. why edge detection better, it's lo

string - How do I use a phrase with php in a mongo text search? -

-
i've got simple mongo query returns result want - db.properties.findone({$text:{$search:'\"eiffel petit louvre\"'}}) however can't seem transpose same query php - $searchstring = '\"eiffel petit louvre\"'; $hotel = $db->properties->findone( array('$text' => array('$search' => $searchstring)) ); this doesn't give me results back. doing wrong? i'm guessing it's string. i've tried escaping backslashes (i don't think should need since string uses single quotes), didn't work. hi had exact same problem. after long trial , error figured out following works: array('$text'=>array('$search'=>"\"$searchstring\""))
