Functions
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("precalcKernel caches production kernel values", "[improc::precalcKernel]")
	Verify precalcKernel returns the same Gaussian and azimuthal kernels as their production generators.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("azBoxKernel is finite at centers and neighboring pixels", "[improc::azBoxKernel]")
	Verify azBoxKernel produces finite normalized kernels at image centers and neighboring pixels.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("azBoxKernel validates widths coordinates and maxAz", "[improc::azBoxKernel]")
	Verify azBoxKernel honors maximum azimuth and validates degenerate configuration values.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("precalcKernel supports odd even and non-square image centers", "[improc::precalcKernel]")
	Verify precalcKernel handles odd, even, and non-square image centers without invalid cached kernels.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("precalcKernel propagates errors and validates lookup bounds", "[improc::precalcKernel]")
	Verify precalcKernel propagates generation errors and rejects invalid lookup coordinates.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("radprofim subtracts a centered radial background", "[improc::radprofim][hciReduce]")
	Verifies the radial-profile subtraction used by HCI preprocessing.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("radprofim excludes masked pixels", "[improc::radprofim][hciReduce]")
	Verifies that masked pixels are excluded from and preserved by radial-profile subtraction.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("medianFilterImage handles HCI azimuthal kernels", "[improc::medianFilterImage][hciReduce]")
	Verifies HCI azimuthal median filtering through a precomputed azimuthal kernel.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("Gaussian filter handles non-square image dimensions", "[improc::imageFilters]")
	Verify that filterImage preserves non-square dimensions with a Gaussian kernel.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("medianSmooth honors exact odd and even full widths", "[improc::medianSmooth]")
	Verify that medianSmooth uses exactly the configured odd or even square window.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("medianSmooth validates widths and output dimensions", "[improc::medianSmooth]")
	Verify that medianSmooth rejects invalid dimensions without modifying caller-owned pixels.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("meanSmooth honors exact even full widths", "[improc::meanSmooth]")
	Verify that meanSmooth uses an exact even-width footprint.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("vectorSmoothMedian honors exact even full widths", "[math::vectorSmoothMedian]")
	Verify that vectorSmoothMedian uses no more than the configured even width.
	unitTest::improcTest::imageFiltersTest::TEST_CASE ("stddevImage subtracts the annular mean for S/N", "[improc::stddevImage]")
	Verify stddevImage centers the signal using the annular mean before calculating S/N.
